CRP is an acute phase protein that correlates with inflammatory disease and is synthesized by hepatocytes during the acute phase response by certain cytokines (IL-1 and TNF Alpha and Beta). CRP levels increase dramatically (up to 1,000 fold) and serve as a useful marker of inflammation in such conditions as bacterial infection, rheumatoid arthritis, viral infections, transplantation rejection, meningitis, myocardial infarction, septicemia, osteomyelitis and others. CRP is also highly correlated to Serum Amyloid A levels. Recombinant CRP is a pentamerized active molecule secreted into culture medium during E.coli fermentation with host cells having human CRP gene, allowing r-hCRP to be excreted without cell lysis. The patented technology specifies only active r-hCRP to be manufactured, which is equivalent to native one originated from human tissues. The recombinant CRP is affinity-purified by use of phosphorylcholine conjugated matrices. As a result, the final product presents the longest stability for 2 years as supplied refrigerated. Recombinant CRP monomer is made of 206 amino acids, and has the same amino acid sequence as native human CRP. Applications: Standard antigen for CRP determination, rhCRP has been evaluated as a secondary reference material to meet standardization of high sensitive CRP assay. High qualified antigen for antibody production. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 6 months after receipt at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
