Product details:
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 CSF.
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.

Serum Amyloid P component also known as SAP P-SAP or APCS protein is a pentraxin family member. It has a molecular mass of approximately 25 kDa. SAP expresses mainly in the liver and circulates in blood plasma. The protein consists of five identical subunits which form a homopentameric structure. This structure enables SAP to bind to amyloid fibrils a defining mechanical action of this protein.
Biological function summary
SAP plays a role in the immune system by recognizing damaged cells and pathogens. It acts as an opsonin marking these cellular targets for phagocytosis. As part of a complex SAP stabilizes extracellular matrix and amyloid deposits. It binds specifically to amyloid fibrils found in various tissues potentially facilitating their removal by immune cells. The protein's binding actions are important for its role in maintaining tissue and fluid homeostasis.
Pathways
SAP is actively involved in the innate immune response and amyloidogenic pathways. It interacts with the complement system to enhance the clearance of cell debris and amyloid fibrils. The complement system is an important component of innate immunity where SAP can engage with complement proteins like C1q. This interaction suggests that SAP plays roles in modulating both inflammation and tissue repair processes.
SAP has significant connections. SAP is related to systemic amyloidosis where it binds to amyloid deposits affecting multiple organs. Moreover SAP has been implicated in Alzheimer's disease due to its interaction with beta-amyloid protein plaques. In these disorders the involvement of SAP aids researchers in understanding the pathological mechanisms and could open avenues for targeted therapies aimed at modulating SAP functions.
