Certain products may require to ship with dry ice and additional dry ice fee may apply.
Searchable Terms for C3bRpurchase
MBS701777 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Complement fragment 3b recptor, C3bR, ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing C3bR. The ELISA analytical biochemical technique of the MBS701777 kit is based on C3bR antibody-C3bR antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect C3bR antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, C3bR. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for C3bR has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any C3bR present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for C3bR is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of C3bR bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Summary for C3bR
This gene is a member of the receptors of complement activation (RCA) family and is located in the 'cluster RCA' region of chromosome 1. The gene encodes a monomeric single-pass type I membrane glycoprotein found on erythrocytes, leukocytes, glomerular podocytes, and splenic follicular dendritic cells. The Knops blood group system is a system of antigens located on this protein. The protein mediates cellular binding to particles and immune complexes that have activated complement. Decreases in expression of this protein and/or mutations in its gene have been associated with gallbladder carcinomas, mesangiocapillary glomerulonephritis, systemic lupus erythematosus and sarcoidosis. Mutations in this gene have also been associated with a reduction in Plasmodium falciparum rosetting, conferring protection against severe malaria. Alternate allele-specific splice variants, encoding different isoforms, have been characterized. Additional allele specific isoforms, including a secreted form, have been described but have not been fully characterized. [provided by RefSeq, Jul 2008]
