Background

CD31/PECAM-1 protein, a pivotal cell adhesion molecule, is essential for leukocyte transendothelial migration (TEM) in most inflammatory conditions. The critical role of Tyr-679 in TEM is underscored by its requirement for efficient trafficking of PECAM1 to and from the lateral border recycling compartment (LBRC), crucial for targeting the LBRC membrane around migrating leukocytes. The trans-homophilic interaction potentially contributes to endothelial cell-cell adhesion via cell junctions, while heterophilic interaction with CD177 plays a role in the transendothelial migration of neutrophils. Homophilic ligation of PECAM1 serves a dual purpose, preventing macrophage-mediated phagocytosis of neighboring viable leukocytes by transmitting a detachment signal, while promoting the macrophage-mediated phagocytosis of apoptotic leukocytes by tethering them to phagocytic cells. Notably, PECAM1 modulates bradykinin receptor BDKRB2 activation and regulates bradykinin- and hyperosmotic shock-induced ERK1/2 activation in endothelial cells. Its interaction with various partners, including BDKRB2, GNAQ, PTPN11, FER, and CD177, further elucidates the intricate molecular mechanisms governing its diverse cellular functions, while its trans-homodimerization is crucial for effective cell-cell interaction. The interaction nuances, such as Ca(2+)-dependency and directness, add layers of complexity to the regulatory roles of CD31/PECAM-1.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
