These pepsinogen 5, group I (pepsinogen A) ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. pepsinogen 5, group I (pepsinogen A) is an alias of the human PGA5 gene, which encodes the protein, pepsinogen A5. Notably, pepsinogen 5, group I (pepsinogen A) is known to play a role in proteolysis, among other functions. The PGA5 protein is described to be 388 amino acid residues in length and 42 kilodaltons in mass. It is known to be a secreted protein. Other names for this target antigen include Pg5, pepsin A-5, and Pepsin A-4. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
