Ready-to-use ELISA kits are available for the detection of Androgen Binding Protein, an alias of the protein, sex hormone binding globulin. The official gene symbol is SHBG. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, guinea pig, and other mammalian. The protein, with a mass of 43.8 kDa and length of 402 residues, is reported to be secreted. It may be known by other names, including: SBP, ABP, testosterone-estradiol-binding globulin, testosterone-binding beta-globulin, testis-specific androgen-binding protein, and sex steroid-binding protein.
