These DSI ELISA kits are immunodetection tools for measuring the levels of DSI in biological samples. DSI is an alias of the human P4HB gene, which encodes the protein, prolyl 4-hydroxylase subunit beta. Notably, DSI is known to play a role in the cellular response to hypoxia and Golgi transport, among other functions. The P4HB protein is described to be 508 amino acid residues in length and 57.1 kilodaltons in mass. It is localized to the ER and cell membrane of the cell. This protein is known to be phosphorylated. Other names for this target antigen include CLCRP1 and ERBA2L.
