other info1 :
Samples: Serum, Plasma, Tissue Homogenate, Feces, Urine and Body Fluids. Assay Type: Sandwich. Detection Range: 31.2 mug/ml - 1000 mug/ml. Sensitivity: 5.0 mug/ml.
other info2 :
Intended Uses: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic or diagnostic applications! It is intended to be determinated C3B concentrations in Canine serum, plasma and other body fluids. Using Purified Canine C3B antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add C3B and C3B antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color under HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of C3B in the samples is then determined by comparing the O.D. of the samples to the standard curve. Intra-assay Precision: Intra-assay CV (%) is less than 15%. Inter-assay Precision: Inter-assay CV (%) is less than 15%. [CV(%) = SD/mean ×100]

ncbi summary :
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]
