IRON CROMAZUROL Colorimetric method Endpoint

€

PRINCIPLE The method is based on the properties of Chromazurol S (CAS), a chromogenic iron-binding dye, that under acidic conditions in presence of cetrimide (CTAB) forms an intense purple complex proportional to the concentration of iron present in the sample. REAGENT COMPOSITION R Chromazurol reagent. Acetate buffer, chromazurol, cetrimide, Mg2+, thiourea, Tween 20. C R:35/10 S :26-37/39-45 STORAGE AND STABILITY Store at 2-8ºC. All the kit compounds are stable until the expiry date stated on the label. Do not use reagents over the expiration date. Store the vials tightly closed, protected from light and prevented contaminations during the use. Discard if appear signs of deterioration: - Presence of particles and turbidity. - - Blank absorbance (A) at 635 nm > 0.575 in 1cm cuvette REAGENT PREPARATION The Reagent is ready-to-use. SAMPLES Serum or heparinized plasma. Centrifuge specimen as soon as possible after collection. Hemolyzed samples are rejected. Ruptured red cells falsely elevate the serum results. Iron in serum is stable for 3 weeks at 2-8ºC and for about 7 days at 20-25ºC. Freeze for longer storage. INTERFERENCES - Lipemia (intralipid >1.25 g/L) may affect the results. - Bilirubin (< 10 mg/dL) does not interfere. - Hemoglobin may affect the results. - Other drugs and substances may interfere MATERIALS REQUIRED - Photometer or colorimeter capable of measuring at 635 ± 20 nm. - Pipettes with disposable plastic tips to measure reagents and samples. - Disposable plastic tubes for the tests. PROCEDURE 1. Bring reagents and samples to room temperature. 2. Pipette into labelled test tubes: (For cal.) R: 1000 uL. + cal.: 50 uL. (For sample) R: 1000 uL. + sample: 50 uL. 3. Mix and let the tubes stand 10 minutes at 37ºC. 4. Read the absorbance (A) of the samples and the standard at 635 nm against the reagent blank. CALCULATIONS A Sample/A Standard x C Standard = ug/dL iron Samples with concentrations higher than 1000 ug/dL should be diluted 1:2 with saline and assayed again. Multiply the results by 2. If results are to be expressed as SI units apply: ug/dL x 0.179 = umol/L. REFERENCE VALUES Men = 60 - 175 ug/dL (10.7 - 31.3 umol/L) Women = 50 - 170 ug/dL (9.0 - 30.4 umol/L) Note: It is recommended that each laboratory establishes its own reference range QUALITY CONTROL The use of a standard to calculate results allows to obtain an accuracy independent of the system or instrument used. To ensure adequate quality control (QC), each run should include a set of controls (normal and abnormal) with assayed values handled as unknowns. If the values are found outside of the defined range, check the instrument, reagents and procedure. Each laboratory should establish its own Quality Control scheme and corrective actions if controls do not meet the acceptable tolerances. CLINICAL SIGNIFICANCE Following intestinal absoption of iron or erythrocyte destruction, iron ions are released into the plasma where they bind to either apotransferrin or apoferritin proteins to form transferrin and ferritin, respectively. The former helps transport iron to bone marrow for erythropoiesis; the latter stores iron in tissues, until is needed. An increase in the iron level in plasma due to rapid destruction of erythrocytes or excesive uptake of iron may also lead to iron overload. The latter causes iron deposition disorders in tissue known as hemosiderosis or hemochromatosis. Conversely, a decrease in the iron level in plasma due to malnutrition or malabsorbtion may lead to excesive depletion in iron storage, resulting in anemia such as iron-deficiency anemia. NOTES - Contamination of glassware with iron will affect the test. Use acid-washed glassware or plastic tubes. - This method may be used with different instruments. Any application to an instrument should be validated to demonstrate that results meet the performance characteristics of the method. It is recommended to validate periodically the instrument. Contact to the distributor for any question on the application method. - - Clinical diagnosis should not be made on findings of a single test result, but should integrate both clinical and laboratory data. ANALYTICAL PERFORMANCE Detection Limit: 10.10 ug/dL Linearity: Up to 1000 ug/dL Precision (expressed in ug/dL): Within-run Mean - 118.8, 204.6 SD - 0.95, 0.59 CV% - 0.81, 0.59 N - 10, 10 Between-run Mean - 118.8, 204.6 SD - 2.71, 3.71 CV% - 2.28, 1.81 N - 10, 10 Sensitivity : 1.6 mAbs / ug/dL iron. Correlation: This assay (y) was compared with a similar commercial method (x). The results were: N = 49 r = 0. 97 y = 0.97x + 0.10 The analytical performances have been generated using on automatic instrument. Results may vary depending on the instrument. IRON CROMAZUROL PDF

Sperm DNA Fragmentation Kit

€

SPERM DNA FRAGMENTATION KIT UNLOCK THE FUTURE OF PARENTHOOD WITH SPERM DNA FRAGMENTATION KIT What is Sperm DNA Fragmentation Kit? The Sperm DNA Fragmentation technique can distinguish between functional and non-functional spermatozoa based on their DNA integrity, identifying which ones are viable for fertilization. This kit evolutionizes the assessment of sperm quality by complementing traditional sperm analysis. While conventional semen analysis focuses solely on sperm concentration, motility, and morphology, it overlooks a crucial parameter: the integrity of the DNA molecule. Interestingly, 15% of men classified as infertile have normal sperm analyses, underscoring the need for a more comprehensive evaluation. Sperm DNA fragmentation kit empowers medical professionals to make informed decisions about the most suitable assisted reproduction techniques for each couple. Employs a controlled DNA denaturation process to facilitate the removal of proteins from each spermatozoon. This method results in the formation of halos composed of DNA loops at the head of healthy sperm, a feature absent in sperm with damaged DNA. Key Features of Sperm DNA Fragmentation Kit - Easy & Quick Assessment: Say goodbye to complex laboratory equipment. Our kit provides a hassle-free, rapid measurement of Sperm DNA Fragmentation. - Comprehensive Insights: Complement traditional semen analysis with specific data on genetic material quality for a holistic evaluation. - Cost-Effective: Avoid expensive and frustrating IVF procedures. Assess Sperm DNA Fragmentation beforehand to guide fertility treatment. - Vital for Success: The integrity of paternal DNA is critical for both natural conception and assisted reproduction, ensuring the best chance of a viable pregnancy Who can use Sperm DNA Fragmentation Kit? Medical professionals rely on information provided by MenidiMedica Biotech solutions as an essential addition to the standard semen analysis when initiating treatment. Sperm DNA damage is a complex process influenced by various factors. Therefore, it is particularly recommended for the following groups: 1. Couples who have experienced recurrent miscarriages. 2. Couples facing unexplained infertility lasting more than six months. 3. Men aged over 40. 4. Individuals who frequently wear tight-fitting clothing. 5. Men with a history of cancer. 6. Men undergoing treatment with prescription medications. 7. Men exposed to harmful substances or toxins. 8. Men who have had urogenital infections. 9. Individuals with unhealthy lifestyle habits, including smoking, physical inactivity, poor dietary choices, or obesity. 10. Cases where the quality of embryos during subsequent cycles of egg donation is suboptimal. 11. Unexplained male infertility. Natural factors such as improper maturation and oxidative stress can lead to disruptions in spermatozoa production within the testicles, resulting in fertility challenges. Why Choose Sperm DNA Fragmentation Kit? - Accurate Evaluation: Obtain precise results with high-contrast halo images using standard bright-field microscopy after Wright staining. - Sperm Identification: Preserve sperm tails for easy differentiation from other cell types and identification of degraded sperm cells with varying halo sizes. - User-Friendly: A simple protocol involving acid treatment and lysis solution makes it easy to assess DNA integrity. - Functional vs. Non-Functional: Identify which spermatozoa are functional for fertilization and distinguish them from non-functional ones. How Does It Work? Our cutting-edge technique is based on the principle that sperm with fragmented DNA do not display the characteristic halo of dispersed DNA loops found in sperm with intact DNA after acid denaturation and nuclear protein removal. Fresh semen samples should be collected in a sterile recipient. The sperm DNA fragmentation assay should be performed immediately once the sperm sample has been obtained or thawed after cryopreservation. a. The spermatozoa are placed in an agarose microgel and evenly distributed onto a slide. b. The sample is subjected to acid denaturation and a lysis solution as part of the treatment process. c. After treatment, the sample undergoes dehydration, staining, and subsequent microscopic visualization for examination of fragmented and non-fragmented DNA. d. To calculate the percentage of sperm with fragmented DNA (SDF), count SDF sperm based on specified criteria and divide by the total sperm counted (N), then evaluate the SDF percentage in relation to established thresholds for SDF levels. Storage Conditions Upon receipt, please store the kit in a location with a temperature range between 2ºC and 30ºC, and ensure it is shielded from exposure to light. Once the kit is opened, it maintains stability for a period of 12 months. Description of kit reagents Every kit contains the necessary to perform 10 assays. The components are: - Agarose Tubes; 10 units - Denaturant Agent 1 mL screw tube - Lysis Solution, six 20 ml bottle each Sperm classification In each sample, a minimum of 300 spermatozoa should be counted, following the specified criteria for categorization: Spermatozoa without DNA fragmentation: - Spermatozoa with big halo: Sperm with halos whose width is equal to or greater than the diameter of the core (referred to as "Big halo"). - Spermatozoa with medium-sized halo: Sperm with halos sized between those with large halos and those with very small halos (referred to as "Medium halo"). - Others: Cells referred to as "others" that do not correspond to spermatozoa, distinguished by the absence of a tail. These cells must not be included in the estimation of the frequency of sperm with fragmented DNA. Spermatozoa with fragmented DNA: - Spermatozoa with small halo: Sperm displaying halos with a width equal to or smaller than 1/3 of the diameter of the core (referred to as "Small halo"). - Spermatozoa without halo: Sperm with no visible halo (referred to as "Without halo"). - Spermatozoa without halo and degraded: Sperm that lack a halo and exhibit irregular or weak staining of the core (referred to as "Degraded").

Bromate Direct

€

QUANTITATIVE DETECTION OF BROMATE IN BREAD Potassium bromate, or simply called bromate, is an oxidiser used to strengthen dough and enhance its elasticity. This helps bake uniform and whitened bread. However, excessive use of potassium bromate results in residual concentrations in bread having potentially harmful effects. Some people who ingested large amounts of bromate had gastrointestinal symptoms such as nausea, vomiting, diarrhea and abdominal pain. Some individuals who ingested high concentrations of bromate also experienced kidney effects, nervous system effects and hearing loss. European bread lacks a specific ingredient: Potassium bromate. Food makers in the United States regularly use this chemical compound to strengthen dough. In fact, this additive is present in more than 100 products. But, Europe, China, and India have banned Potassium bromate due to concerns that it may be a carcinogen.
