Human Cluster Of Differentiation 2, Active Protein, Cat#RPU60382
SDS-PAGE
Cluster of Differentiation 2 (CD2) is a surface antigen found on all peripheral blood T-cells. CD2 functions as an activator of T lymphocytes and thymocytes. Mature human CD2 consists of a 185 amino acid (aa) extracellular domain (ECD) with an Ig-like V-type and an Ig-like C2 type domain, a 26 aa transmembrane segment, and a 116 aa cytoplasmic tail. Cluster of Differentiation 5 (CD5) has been identified as an interactor of CD2, thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human CD2 and recombinant human CD5. Briefly, CD2 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to CD5-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-CD2 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 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 nm immediately. The binding activity of recombinant human CD2 and recombinant human CD5 was shown, the EC50 was 1.88 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.
