This kit uses Sandwich-CLIA as the method. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human ApoH. Standards or samples are added to the appropriate micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human ApoH and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human ApoH, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured spectrophotometrically by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Human ApoH. The concentration of Human ApoH in the samples can be calculated by comparing the RLU of the samples to the standard curve.
UniProt Protein Function: | APOH: Binds to various kinds of negatively charged substances such as heparin, phospholipids, and dextran sulfate. May prevent activation of the intrinsic blood coagulation cascade by binding to phospholipids on the surface of damaged cells. |
UniProt Protein Details: | Protein type:Secreted; Lipid-binding; Secreted, signal peptide Chromosomal Location of Human Ortholog: 17q24. 2 Cellular Component: extracellular matrix; extracellular space; chylomicron; cell surface Molecular Function:heparin binding; identical protein binding; protein binding; phospholipid binding; glycoprotein binding; lipid binding Biological Process: negative regulation of angiogenesis; negative regulation of myeloid cell apoptosis; triacylglycerol metabolic process; positive regulation of blood coagulation; negative regulation of fibrinolysis; negative regulation of endothelial cell proliferation; positive regulation of lipoprotein lipase activity; negative regulation of blood coagulation; triacylglycerol transport; blood coagulation, intrinsic pathway; plasminogen activation; regulation of fibrinolysis |
NCBI Summary: | Apolipoprotein H has been implicated in a variety of physiologic pathways including lipoprotein metabolism, coagulation, and the production of antiphospholipid autoantibodies. APOH may be a required cofactor for anionic phospholipid binding by the antiphospholipid autoantibodies found in sera of many patients with lupus and primary antiphospholipid syndrome, but it does not seem to be required for the reactivity of antiphospholipid autoantibodies associated with infections.

As the RLU values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.
