Anti-Porcine IL-1α

E. coli-Derived Recombinant Porcine Interleukin-1α

This monoclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 - 7.3 containing 5.0% w/v trehalose with no calcium, magnesium or preservatives present.

The lyophilized antibody can be stored desiccated at -20°C to -70°C for up to twelve months. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid repeated freeze thaw cycles. No detectable loss of activity was observed after six months.

Clone 85733 recognizes an epitope on porcine IL-1α. This antibody shows almost 100% cross-reactivity with rhIL-1α, rmIL-1α and rrIL-1α.

IL-1R1 is an 80 kD transmembrane glycoprotein and a member of the Ig superfamily. IL-1 binds both IL-1R1 and IL-1R2. The ligands IL-1α and IL-1β only commence when binding IL-1R1 because IL-1R2 acts as a decoy receptor and competitively antagonizes the binding of IL-1α and IL-1β, thereby reducing their biological effects. Binding of the ligands to IL-1R1 is enhanced by an accessory protein, IL-1R-AcP. IL-1α can exist as either a 31 kD precursor or an 18 kD mature form. IL-1α is a proinflammatory cell-associated cytokine and IL-1β is a 17.5 kD proinflammatory secreted cytokine. Both IL-1α and IL-1β bind to the same receptor and have similar properties that include stimulation of thymocyte proliferation via IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity and the ability to stimulate the release of prostaglandin and collagenase from synovial cells. Furthermore, IL-1β mediates a variety of immune and inflammatory responses. IL-1β is a major cause of severe inflammation in the mouse model of Crohn’s Disease, which makes IL-1β an important target for this disease.
