For in vitro diagnostic use only. PRINCIPLE OF THE TEST The principle of the following enzyme immunoassay test follows the typical competitive binding scenario. Competition occurs between an unlabeled antigen (present in standards, control and patient samples) and an enzyme-labelled antigen (conjugate) for a limited number of antibody binding sites on the microwell plate. The washing and decanting procedures remove unbound materials. After the washing step, the enzyme substrate is added. The enzymatic reaction is terminated by addition of the stopping solution. The absorbance is measured on a microtiter plate reader. The intensity of the colour formed is inversely proportional to the concentration of 3α Diol G in the sample. A set of standards is used to plot a standard curve from which the amount of 3α Diol G in patient samples and controls can be directly read. CLINICAL APPLICATIONS 5α-Androstane-3α, 17β-diol glucuronide is a C19 steroid and is either abbreviated as 3α Diol G, 5α Diol G or simply, α Diol G. It is produced mainly as a metabolite of testosterone and dihydrotestosterone (DHT). It is largely produced in target peripheral tissues such as the skin, especially around hair follicles. The stimulation by large amounts of 3α Diol G leads to excessive hair formation, notably where hair is not normally present in women. In recent years the interest in the measurement of this steroid has increased among clinical investigators studying women suffering from idiopathic hirsutism. Among the steroids known to be precursors for 3α Diol G are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEAS), dihydrotestosterone (DHT), androstenedione and testosterone. Only 3α Diol G has been shown to increase with hirsutism and decrease with treatment. This correlation has also been demonstrated in patients with polycystic ovarian syndrome (PCO). 3α Diol G determinations have therefore proved to be a useful indicator in a variety of ways including monitoring the progress of treatment of idiopathic hirsutism and women with PCO. Furthermore, diabetic patients (both men and women) under cyclosporine A therapy have shown increased 3α Diol G levels, a side effect resulting in the appearance of hair in previously hairless areas. 上海玉博生物技術(shù)有限公司在為生命科學(xué)領(lǐng)域提供豐富的產(chǎn)品與信息資源方面處于國內(nèi)**地位,公司提供的產(chǎn)品涵蓋了二十多個(gè)國家近五十萬種產(chǎn)品,而且產(chǎn)品的數(shù)量與信息在不斷的增長和更新,公司提供的產(chǎn)品能夠使生命科學(xué)工作者加快對生物化學(xué),分子生物學(xué),細(xì)胞生物學(xué)以及蛋白質(zhì)組學(xué)研究的認(rèn)知,以及分子診斷和臨床醫(yī)學(xué)領(lǐng)域的應(yīng)用。
