PSAP ELISA kits are immunoassay tools for the measurement of the protein prosaposin, which is encoded by the PSAP gene in humans. Functionally, this protein is known to be involved in autophagy pathways and the metabolism of lipids. The canonical protein structure is reported to have an amino acid sequence of 524 residues and a mass of 58.1 kDa. It is known to be localized in the lysosomes and is secreted. As many as 3 protein isoforms have been reported. The protein has been noted to be post-translationally cleaved and glycosylated. The PSAP gene has been associated with the disease, Combined saposin deficiency. Other alias names for this target include PARK24, PSAPD, SAP1, SAP2, proactivator polypeptide, saposin-A, saposin-B, and GLBA.
The detection range for different PSAP ELISA kits can vary, with some assays measuring target concentrations as low as 14 pg/mL and as high as 50 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
