General description

Interleukin-1 beta (UniProt; also known as IL-1 beta, IL-1b, IL-1beta) is encoded by the Il1b gene (Gene ID 16176) in murine species. Interleukin-1 (IL-1) is a cytokine that plays a central role in the regulation of acute and chronic inflammation. Two forms of IL-1, IL-1 and IL-1 , are transcribed from two separate genes and mediate similar, but not completely overlapping, biological effects via the membrane-bound IL-1 type 1 receptor (IL-1R1). Studies utilizing Il1a- and Il1b-knockout mice showed that IL-1 , but not IL-1 , is involved in T-cell-dependent antibody production via antigen-specific T-cell activation. IL-1 binding to the extracellular domain of IL1R1 promotes the recruitment of the IL-1 receptor accessory protein and subsequent signal transduction mediated by the cytoplasmic domains of IL-1R1 and IL1-R2. The IL-1 type 2 receptor (IL1R2) is unable to initiate signaling and only acts as a decoy receptor. Soluble receptors for IL-1 (sIL-1Rs) are produced by proteolytic cleavage of membrane-bound receptors or by alternative splicing and act as natural inhibitors by competing against membrane-bound IL1Rs for IL-1 binding. Murine IL-1 beta is produced with a propeptide sequence (a.a. 1-117), which is removed posttranslationally to yield the mature (a.a. 118-269) protein.

Immunogen

KLH-conjugated linear peptide corresponding to a region within the C-terminal half of the mature murine and rat IL-1beta sequence.

Linkage

Replaces: AB1413

Other Notes

Concentration: Please refer to lot specific datasheet.

Physical form

Purified rabbit polyclonal antibody in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.

Affinity purified.

Quality

Evaluated by Western Blotting in NIH/3T3 cell lysate.

Western Blotting Analysis: 2 µg/mL of this antibody detected IL-1beta in 10 µg of NIH/3T3 cell lysate.

Specificity

This rabbit polyclonal antibody detected both the ~17 kDa mature and ~30 kDa pro-form of murine IL-1beta. The corresponding sequence in human IL-1beta differs from that of the immunogen by only one amino acid. Immunogen sequence is not found in IL-1alpha.

Storage and Stability

Stable for 1 year at 2-8°C from date of receipt.

Target description

~17/30 kDa observed. 17.39/30.93 kDa (mouse mature/pro-form), 17.32/30.64 kDa (rat mature/pro-form) calculated. Uncharacterized bands may be observed in some lysate(s).
