These GAGE9 ELISA kits are immunodetection tools for measuring the levels of GAGE9 in biological samples. GAGE9 is an alias of the human PAGE4 gene, which encodes the protein, PAGE family member 4. Notably, GAGE9 is known to play a role in the regulation of apoptosis and the response to oxidative stress, among other functions. The PAGE4 protein is described to be 102 amino acid residues in length and 11.2 kilodaltons in mass. It is localized to the nucleus, mitochondria, and cytoplasm of the cell. In terms of tissue specificity, it is noted to be expressed at basal lvels in the adult normal prostate gland but is highly up-regulated in the fetal prostate and prostate cancer cells. This protein is known to be phosphorylated. Other names for this target antigen include CT16.7 and GAGEC1.
