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.

Product Details

Verified Reactivity
Mouse, Rat
Antibody Type
Host Species
Armenian Hamster
E. coli -expressed, recombinant mouse IL-1β
0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is < 1.0 EU/mg of the protein (< 0.1 pg/µg of the protein) as determined by the LAL test.
The GoInVivo™ antibody was purified by affinity chromatography.
The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL.
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. This GoInVivo™ solution contains no preservative; handle under aseptic conditions.

ELISA Capture - Quality tested
ELISPOT Capture, Depletion, IHC-F, IP, Neut, WB - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA capture applications, a concentration range of 2.0 - 6.0 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of IL-1β recombinant protein ranging from 2000 to 30 pg/mL are recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

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.
