Assay Principle
This one-step sandwich ELISA quantifies mouse E-selectin in cell culture supernatants, serum and plasma (heparin, citrate). The strips are pre-coated with a capture antibody; sample and an HRP-linked detection antibody are incubated together, so the assay needs fewer wash and incubation steps than a standard sandwich ELISA (the supplier markets the Quick format as a 90-minute assay). TMB develops color in proportion to the bound target, and the plate is read at 450 nm.
E-selectin (SELE, CD62E) is an adhesion molecule expressed on endothelial cells after activation by inflammatory cytokines such as TNF and IL-1. It binds sialyl-Lewis X ligands on leukocytes, allowing neutrophils and other white cells to tether and roll along the vessel wall, and soluble E-selectin is a common marker of endothelial activation.
