Description

The PathScan^® Total CD31 (PECAM-1) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of CD31 (PECAM-1) protein. A CD31 (PECAM-1) mouse mAb has been coated onto the microwells. After incubation with cell lysates, the CD31 (PECAM-1) proteins are captured by the coated antibody. Following extensive washing, a CD31 (PECAM-1) biotinylated detection mAb is added to detect captured CD31 (PECAM-1) proteins. HRP-linked Streptavidin is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of absorbance for the developed color is proportional to the quantity of CD31 (PECAM-1) protein.

*Antibodies in this kit are custom formulations specific to the kit.

Specificity/Sensitivity

PathScan^® Total CD31 (PECAM-1) Sandwich ELISA Kit detects endogenous levels of CD31 (PECAM-1) protein in human cells, as shown in Figure 1. The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

CD31 (Platelet Endothelial Cell Adhesion Molecule-1: PECAM-1), a member of the Ig superfamily of cell adhesion molecules, is expressed by circulating platelets, monocytes, neutrophils, some T cells, and endothelial cells and modulates cell adhesion, endothelial cell migration, and angiogenesis (1). CD31 is phosphorylated on Tyr686 at the cytoplasmic carboxy-terminal tail upon various stimuli (e.g. mechanical or oxidative stress), presumably by Src family members (2). The tyrosine phosphorylation mediates associations with a number of SH2 domain-containing binding partners such as PI3 kinase, SHIP, PLCγ, and SHP-2. Thus, CD31 serves as a scaffold for various signaling molecules (3).
