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 HABP1/C1QBP. 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 HABP1/C1QBP 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 HABP1/C1QBP, 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 HABP1/C1QBP. The concentration of Human HABP1/C1QBP in the samples can be calculated by comparing the RLU of the samples to the standard curve.
UniProt Protein Function: | C1QBP: a multifunctional and multicompartmental protein involved in inflammation and infection processes, ribosome biogenesis, regulation of apoptosis, transcriptional regulation and pre-mRNA splicing. Originally identified via its binding interactions with Splicing Factor (SF-2). Multiple, diverse binding partners of C1QBP were subsequently identified, including the globular heads of complement component C1q, hyaluronic acid, selected protein kinases, the tumor suppressor ARF, and multiple antigens of bacterial and viral origin. Overexpressed in a number of cancer cell types, and has been implicated in the Warburg effect, whereby cancer cells shift their metabolism from oxidative phosphorylation to glycolysis. Inhibits the Mitochondrial Permeability Transition (MPT) pore, possibly serving a protective function against damage from oxidative stress. Binding to C1q inhibits C1. In complex with cytokeratin-1/KRT1 is a high affinty receptor for kininogen-1/HMWK. The secreted form may enhance both extrinsic and intrinsic coagulation pathways. The cell surface form may require docking with transmembrane proteins for downstream signaling which might be specific for a cell-type or response. Belongs to the MAM33 family. |

NCBI Summary: | The human complement subcomponent C1q associates with C1r and C1s in order to yield the first component of the serum complement system. The protein encoded by this gene is known to bind to the globular heads of C1q molecules and inhibit C1 activation. This protein has also been identified as the p32 subunit of pre-mRNA splicing factor SF2, as well as a hyaluronic acid-binding protein. [provided by RefSeq, Jul 2008] |

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.
