Sex hormone-binding globulin (SHBG) is a glycoprotein produced primarily in the liver that serves as the major transport protein for sex hormones including testosterone, dihydrotestosterone, and estradiol in blood circulation. SHBG regulates the bioavailability of these hormones by binding them with high affinity, thereby controlling the amount of free, biologically active hormones available to target tissues. Changes in SHBG levels are associated with various physiological and pathological conditions, making it an important biomarker in endocrinology research and clinical diagnostics related to reproductive health, metabolic disorders, and hormonal imbalances.
The Human sex hormone-binding globulin SHBG ELISA Kit (CSB-E08232h) provides quantitative measurement of SHBG in human samples. This sandwich ELISA works with serum, plasma, and tissue homogenates. Detection range spans 1.56 pmol/L to 100 pmol/L with sensitivity of 0.39 pmol/L. The assay requires 50-100 μL sample volume and takes 1-5 hours to complete, with detection performed at 450 nm wavelength.
