Ready-to-use ELISA kits are available for the detection of Inhibin Beta E, an alias of the protein, inhibin subunit beta E. The official gene symbol is INHBE. The kits can detect several species variants of the protein, including: mouse, rat, and bovine. The protein, with a mass of 38.6 kDa and length of 350 residues, is reported to be secreted. It is a member of the TGF-beta family and may be known by other names, including: inhibin beta E subunit, activin beta-E chain, and inhibin beta E chain.
