  • 产品描述：

    The Rat 3-oxo-5-alpha-steroid 4-dehydrogenase 2 (SRD5A2) ELISA kit is the ultimate tool for researchers seeking to quantify SRD5A2 levels in samples of rat serum, plasma, tissue homogenates, and cell lysates.

    The SRD5A2 protein, also known as 3-oxo-5-alpha-steroid 4-dehydrogenase 2, is involved in processing androgens, which are hormones that direct male sexual development,making it an essential protein for researchers in this field. Our ELISA kit is designed to provide fast, accurate, and reliable results, allowing researchers to measure SRD5A2 levels with high sensitivity and precision.

    With a detection range of 6 pg/mL to 1200 pg/mL and a sensitivity of 3 pg/mL, this ELISA kit delivers precise and accurate results. The assay time is just 1-5 hours, and the sample volume required is only 50-100ul, making it a highly efficient tool for researchers.

    The kit uses a competitive assay principle, enabling quantitative measurement of SRD5A2 levels in samples. The detection wavelength is 450 nm, making it easy to read and interpret results.

  • 功能：
    Converts testosterone (T) into 5-alpha-dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.
