Human Protein Tyrosine Phosphatase Receptor Type C, Active Protein, Cat#RPU60406
SDS-PAGE
Protein Tyrosine Phosphatase Receptor Type C (CD45) is one of the most abundant leukocyte cell surface glycoproteins and is expressed exclusively upon cells of the hematopoietic system. CD45 functions positively to regulate lymphocyte activation by servesing to dephosphorylate and activate members of the Src-tyrosine kinase family. it has been reported that SEMA4D can associate with the phosphatase CD45 at the surface of T cells and that triggering of CD45 on T cells, using monoclonal antibodies (mAb), induces shedding of SEMA4D. Thus a functional binding ELISA assay was conducted to detect the interaction of recombinant human CD45 and recombinant human SEMA4D. Briefly, biotin-linked CD45 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to SEMA4D-coated microtiter wells and incubated for 1h at 37°C. Wells were washed with PBST 3 times and incubation with Streptavidin-HRP for 30min, then 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 nm immediately. The binding activity of CD45 and SEMA4D was shown, the EC50 for this effect is 6.47 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.
