Background
Leukocytes adhere to the blood vessel endothelium during extravasation in postcapillary venules of lymph nodes. In addition, leukocyte adhesion occurs in the capillaries and small venules at any site in the body after onset of inflammation. This response is immediate and involves a cascade of adhesion receptors. At the endothelial surface members of the selectin and immunoglobulin superfamilies participate in this cascade. Selectins are C-type cell surface lectins that play a role in leukocyte adhesion to the blood vessel wall endothelium. E-selectin (CD62E) is an endothelial cell specific selectin that is expressed only after activation with proinflammatory cytokines. In vitro experiments have shown that IL-1, TNFα and bacterial wall components like lipopolysaccharides induce the transcription of E-selectin in a NFκB dependent signalling cascade. E-selectin has been associated with blood vessel endothelium in diverse inflammatory situations.

Source
UZ4 is a Rat monoclonal IgM antibody derived by fusion of SP2/0 Mouse myeloma cells with spleen cells from a Lewis Rat immunized with LPS-activated mlEND1 cells expressing E-selectin at their cell surface.

Product
Each vial contains 100ul 1 mg/ml purified monoclonal antibody in PBS containing 0,09% sodium azide.

Formulation: Each vial contains 100ul 1 mg/ml purified monoclonal antibody in PBS containing 0,09% sodium azide.

Specificity
UZ4 recognizes the minimal amino acid consensus sequence CXKKKL present in the lectin domain of both murine and Human E-selectin.

Applications
UZ4 is suitable for immunoblotting, ELISA, immunoprecipitation and flow cytometry (dilution 1:500). To analyze E-selectin protein in frozen sections we refer to the anti E-selectin monoclonal antibodies UZ5, UZ6, and UZ7. For a functional UZ4 antibody that inhibits leucocyte adhesion to murine and Human activated endothelial cells refer to the E-selectin antibody for in vivo use which does not contain azide.

Storage
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
