Description

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.

Formulation
0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.1 EU/µg of the protein (<0.01 ng/µg of the protein) as determined by the LAL test.
Preparation
The LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
Concentration
1.0 mg/ml
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. This LEAF™ solution contains no preservative; handle under aseptic conditions.
Application

ELISA Capture - Quality tested
ELISPOT Capture, Depletion, IHC-F, IP, Neut, WB - Reported in the literature

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-1β 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-1β bioactivity1, in vivo cytokine depletion5, immunohistochemical staining of frozen sections6, Western blotting7, and the study of endotoxin shock8.

Related FAQs

Does BioLegend test each LEAF™ antibody by functional assay?

No, BioLegend does not test LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this LEAF™/Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
