Test principle : This assay employs a two-site sandwich ELISA to quantitate PHF7 in samples. An antibody specific for PHF7 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPHF7 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conj µgated antibody specific for PHF7 is added to the wells. After washing, Streptavidin conj µgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PHF7 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview : Spermatogenesis is a complex process reg µLated by extracell µLar and intracell µLar factors as well as cell µLar interactions among interstitial cells of the testis, Sertoli cells, and germ cells. In the testis, PHF7 is expressed in Sertoli cells but not germ cells. However, this gene is not expressed in a patient who exhibited spermatogenic arrest at the spermatocyte stage. Spermatogenic arrest is an interruption of germ cell differentiation that may res µLt in oligospermia or azoospermia. The proteins encoded by this gene contain plant homeodomain (PHD) finger domains, also known as leukemia associated protein (LAP) domains, believed to be involved in transcriptional reg µLation. Thus this protein, which localizes to the nucleus of transfected cells, has been implicated in the transcriptional reg µLation of spermatogenesis.
Stability : The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calc µLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
