Recombinant Human CD31/PECAM-1 Protein, CF Summary

Product Specifications

Purity
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When 5 x 104 cells/well are added to rhCD31 coated plates (3.3 μg/mL, 100 μL/well) in the presence of 20 ng.mL PMA, approximately 50-65% will adhere after 30 minutes at 37°C.
Source
Chinese Hamster Ovary cell line, CHO-derived human CD31/PECAM-1 protein
Gln28-Lys601
Accession #
N-terminal Sequence
Analysis
No results obtained: Gln28 predicted
Predicted Molecular Mass
64.5 kDa

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: CD31/PECAM-1

The CD31 adhesion molecule, also known as PECAM-1, is expressed in large amounts on endothelial cells at intercellular junctions and on T cell subsets, and to a lesser extent on platelets and most other leukocytes such as monocytes and neutrophils. CD31 binds to itself homotypically, and also to the leukocyte integrin alpha v beta 3 heterotypically. CD31 is required for the transendothelial migration of leukocytes through intercellular junctions of vascular endothelial cells. CD31 has been found in human plasma, and the presence of this circulating isoform is suggested to modulate the transendothelial migration of leukocytes.
