Biolegend, 503505, Biotin anti-mouse / rat IL-1β Antibody, 50μg

IL-1 refers to two proteins, IL-1α and IL-1β which are the products of distinct genes, but which are recognized by the same cell surface receptors. IL-1β is a potent immuno-modulator which mediates a wide range of immune and inflammatory responses including the activation of B and T cells. The B122 antibody reacts with the precursor and mature secreted forms of mouse IL-1β. This antibody also recognizes rat IL-1β. The B122 antibody can neutralize the bioactivity of natural or recombinant IL-1β.
50μg
Verified Reactivity: Mouse, Rat
Antibody Type: Monoclonal
Host Species: Armenian Hamster
Immunogen: E. coli -expressed, recombinant mouse IL-1β
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
Application: ELISA - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by ELISA assay.
Application Notes: ELISA or ELISPOT Capture3: The purified B122 antibody is useful as the capture antibody in a mouse IL-1ß sandwich ELISA or ELISPOT assay, when used in conjunction with the biotinylated Poly5158 antibody (Cat. No. 515801) as the detecting antibody. The LEAF™ purified antibody is suggested for ELISPOT capture. Certain formats of clone B122 have been reported for in vitro neutralization of IL-1ß bioactivity1, in vivo cytokine depletion5, immunohistochemical staining of frozen sections6, Western blotting7, and the study of endotoxin shock8.
