These HYS ELISA kits are immunodetection tools for measuring the levels of HYS in biological samples. HYS is an alias of the human MEA1 gene, which encodes the protein, male-enhanced antigen 1. Notably, HYS is known to play a role in cell differentiation and male gonad development, among other functions. The MEA1 protein is described to be 185 amino acid residues in length and 19.9 kilodaltons in mass. In terms of tissue specificity, it is reported to be highly expressed in testis. Other names for this target antigen include . Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
