These phosphatase, orphan 1 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. phosphatase, orphan 1 is an alias of the human PHOSPHO1 gene, which encodes the protein, phosphoethanolamine/phosphocholine phosphatase 1. The protein is a reported phosphatase that has a high activity toward phosphoethanolamine (PEA) and phosphocholine (PCho). The PHOSPHO1 protein is 267 amino acid residues in length and 29.7 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is noted to be expressed at sites of mineralization in bone and cartilage. Other names for this target antigen include phosphoethanolamine/phosphocholine phosphatase and phosphatase, orphan 1.
