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.

Technical Data Sheet (pdf)

Product Details

Source

Mouse IL-1β, amino acids Val118-Ser269 (Accession # NM_008361) was expressed in E. coli, approximately 17 kD.

Formulation

Lyophilized in sterile-filtered PBS, pH 7.2, containing 1% BSA, 0.09% sodium azide, and protease inhibitors.

Concentration

Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)

Storage & Handling

Unopened vials can be stored between 2°C and 8°C until the expiration date. Prior to use, reconstitute the lyophilized powder with 0.2 mL of PBS containing a carrier protein (e.g., 1% BSA, protease free), pH7.4. Re-cap vial, vortex. Allow the reconstituted standard to sit at room temperature for 15 minutes, vortex again to mix completely. The reconstituted standard stock solution can be aliquoted into polypropylene vials and stored at -70°C for up to one month. Do not re-use diluted standards. Avoid repeated freeze/thaw cycles.

Application

ELISA

Recommended Usage

Each lot of this protein is quality control tested by ELISA assay. For use as an ELISA standard, a standard curve comprised of doubling dilutions from 2000 pg/ml to 31.3 pg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This IL-1ß protein is useful as a standard for a mouse IL-1ß sandwich ELISA, using unlabeled B122 antibody (Cat. No. 503502) for capture and biotinylated Poly5158 antibody (Cat. No. 515801) for detection.
