Human IL-1β Neutralizing Antibody (clone 4H5) - Monoclonal Mouse IgG1
3 x 100 µg
Neutralizing monoclonal antibody against human interleukin 1 beta
Anti-hIL-1β-IgG (clone 4H5) is a monoclonal antibody (mAb) specific for human interleukin 1 beta (hIL-1β). It is produced in hybridomas and purified by affinity chromatography. This antibody has been selected for its ability to efficiently neutralize the biological activity of hIL-1β.
IL-1β is a soluble pro-inflammatory cytokine that plays a critical role in the host response to infection and injury .
- A potent and specific neutralizing mAb against hIL-1β
- Provided azide-free
- No cross-reactivity with human IL-1α, murine IL-1α, or murine IL-1β
- Each lot is functionally tested

Interleukin-1 beta (IL-1β) is a secreted pro-inflammatory cytokine . It participates in the generation of systemic and local responses to infection and injury . IL-1β is produced by activated macrophages as a pro‑protein, which is cleaved by caspase 1, an enzyme that is activated within the inflammasome multiprotein complex .
The resulting mature IL-1β is secreted and binds to the IL-1RI receptor triggering the formation of the IL-1R1/IL-1R3/MyD88 complex and inducing MyD88‑mediated intracellular signaling. This leads to the activation of the transcription factor NK-κB signaling, and the JNK and p38 mitogen‑activated protein kinase pathways, which induce the expression of inflammatory cytokines and chemokines, such as IL-6 and IL-8 .
