Pig C Reactive Protein, Active Protein, Cat#RPU60721
SDS-PAGE
Reactive protein (CRP) is an annular (ring-shaped), pentameric protein found in blood plasma, whose levels rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells (and some types of bacteria) in order to activate the complement system via C1q. Besides, Coagulation Factor II (F2) has been identified as an interactor of CRP, thus a functional binding ELISA assay was conducted to detect the interaction of recombinant pig CRP and recombinant rat F2. Briefly, CRP was diluted serially in PBS with 0.01% BSA (pH 7.4). Duplicate samples of 100 μl were then transferred to F2-coated microtiter wells and incubated for 1h at 37°C. Wells were washed with PBST and incubated for 1h with anti-CRP pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody for 1h at 37°C, wells were aspirated and washed 5 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37°C. Finally, add 50 uL stop solution to the wells and read at 450/630 nm immediately. The binding activity of recombinant pig CRP and recombinant rat F2 was shown, the EC50 for this effect is 0.02 ug/mL.

Let customers speak for us

from 218 reviews

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
