These OV-1 ELISA kits are immunodetection tools for measuring the levels of OV-1 in biological samples. OV-1 is an alias of the human PTP4A2 gene, which encodes the protein, protein tyrosine phosphatase 4A2. Notably, OV-1 is known to play a role in protein dephosphorylation, among other functions. The PTP4A2 protein is 167 amino acid residues in length and 19.1 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cell membrane and cytoplasm of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. Other names for this target antigen include HH13, HH7-2, and HU-PP-1. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
