GT AZFScreen
GT AZFScreen kit is an STS-based (Sequence-Tagged Sites) kit for rapid and accurate detection of Y chromosome microdeletions in cases of male infertility. GT AZFScreen kit is developed for the detection of Y chromosome microdeletions, a frequent genetic cause of infertility in men. Infertility is regarded as a critical problem for most couples. It affects 15-20 % of reproductive-age couples worldwide. Male infertility contributes to about 20-30% of these cases, out of which Y chromosome microdeletions cause 5-10 %.
GT AZFScreen kit includes 19 markers (including 16 STS, 2 SD [Segmental Duplication] and 1 STR). Primer design followed European Molecular Genetics Quality Network guidelines.
The GT AZFScreen kit can also detect Klinefelter Syndrome (47, XXY), another cause of male infertility in men. However, we recommend the use of GT AZFScreen Plus for detection of Klinefelter Syndrome. GT AZFScreen kit performance has been validated with extensive testing using Applied Biosystems™ 3500/xL and 3130/xl platforms for detection and analysis on more than 500 samples, either as normal, with Klinefelter Syndrome, deletions of AZFa, AZFb, AZFc, AZFd, or any combination of these deletions.
