Product overview
Human SAP (APCS) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of human SAP in plasma, serum, urine, and cell culture supernatants.
A SAP specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a SAP specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of SAP captured in plate.
The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Research areas
-
Function
Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells. May also function as a calcium-dependent lectin. -
Tissue specificity
Found in serum and urine. -
Involvement in disease
Note=SAP is a precursor of amyloid component P which is found in basement membrane and associated with amyloid deposits. -
Sequence similarities
Belongs to the pentaxin family.
Contains 1 pentaxin domain. -
Post-translational
modificationsN-glycosylated with a complex biantennary oligosaccharide chain with a sialic acid at the end (disialo-SAP). Monosialo-SAP as well as asioalo-SAP are also detected (PubMed:15174148). -
Cellular localization
Secreted. - Information by UniProt
