BD Pharmingen™
Mouse (QC Testing)
Armenian Hamster IgG, λ1
Mouse IL-1β Protein
ELISA (Routinely Tested), Neutralization (Tested During Development), Immunoprecipitation (Reported)
1.0 mg/ml
No azide/low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Recommended Assay Procedures

ELISA:  Purified Hamster Anti-Mouse IL-1β (Cat. No. 550605) has been reported to be useful as a capture antibody for sandwich ELISA measuring mouse IL-1β protein levels.   For measuring mouse IL-1β in complex biological samples, such as serum or plasma, investigators are highly encouraged to use the BD OptEIA™ Mouse IL-1β ELISA Set (Cat. No 559603).

Immunoprecipitation:  Purified Hamster Anti-Mouse IL-1β (clone B122) has been reported to be useful for the immunoprecipitation of both natural and recombinant forms of mouse IL-1β protein.  Please note that this antibody is not routinely tested for this application.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at

The B122 antibody recognizes the precursor and mature secreted forms of the mouse IL-1β protein. B122 neutralizes the biological activity of mouse IL-1β, but not the biological activities of mouse IL-1α nor human IL-1β. B122 does not recognize mouse IL-2, IL-4, IL-6, IL-10, TNF or IFN-γ. This antibody also recognizes rat IL-1β. The immunogen used to generate the B122 hybridoma was a purified, mature form of the mouse IL-1β protein.

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.
