Wright Stain Sperm DNA Fragmentation Test Validated Reagent Kit 40 Tests/Kit
|
Easy to perform and score, Validated reagent kit for Sperm DNA fragmentation test (SCD method)
1. The kit is designed to evaluate the DNA intactness in human sperm. 2. The assay is to provide medical evidence for the etiology of
infertility, the prediction of assisted reproductive pregnancy
outcome 3. The reagent kit has excellent staining for sperm, easy to
identify the fragmented sperm. The head halo of non-fragmented
sperm is 4. Equipped with Specimen SCD preservation, fresh semen could be
stored for up to half a month and tested in batch. Easy for 5. The required device is general microscope and 80℃ water bath. Without the need for complex laboratory equipment. 6. With wide range of users.
【Test principle】 Sperm Chromatin Dispersion (SCD) method: The basis of the test lies in the differential response offered by the nuclei of spermatozoa with fragmented DNA compared to those with their DNA intactness. The controlled denaturation of the DNA followed by the extraction of the nuclear proteins, gives rise to partially deproteinized nucleoids in which the DNA loops expand, forming halos of chromatin dispersion. However, the spermatozoa nucleoids whose DNA is fragmented, either do not develop a dispersion halo or the halo is minimal.
【Reference value】 *The normal reference value: the percentage of sperm with fragmented DNA < 25%.
The identification of DNA fragmented sperm: the head of sperm only produce small halos or not, and the thickness of the halos in one side is less than 1/3 of the smallest diameter of the head of sperm
