ABOUT
Human IL-1β protein - Mammalian cell-expressed, tag-free, carrier-free
Recombinant human IL-1β is a high-quality and biologically active cytokine, validated using proprietary IL-1β reporter cells. This member of the IL-1/TLR cytokine superfamily is produced in CHO cells to ensure protein glycosylation and bona fide 3D structure.
Recombinant human IL-1β can be used together with HEK-Blue™ IL-1β cells for the screening of inhibitory molecules, such as Nidanilimab, a therapeutic monoclonal antibody targeting IL-1β (see figures).
Key features
- Each lot is validated using HEK-Blue™ IL-1β cells
- Endotoxin < 0.1 EU/µg
- 0.2 µm sterile-filtered
Applications
- IL-1β detection and quantification assays (positive control)
- Screening and release assays for antibodies blocking IL-1β signaling
- Screening and release assays for engineered IL-1β proteins
Interleukin 1 beta (IL-1β) is a secreted pro-inflammatory cytokine that generates systemic and local responses to infection and injury. Dysregulated production of IL-1β contributes to inflammatory diseases such as cryopyrin-associated periodic syndrome (CAPS), familial mediterranean fever (FMF), and systemic juvenile idiopathic arthritis (SJIA).
All InvivoGen products are for internal research use only, and not for human or veterinary use.

Details
IL‑1 is a secreted pro‑inflammatory cytokine that plays a critical role in immune responses and inflammation [1]. It exists in two distinct isoforms, IL-1α and IL-1β, which are produced as pro-proteins by activated macrophages. IL-1β is cleaved by caspase-1 [2] while IL-1α is cleaved by calcium‑activated calpain or caspase-5 (or its murine ortholog caspase-11) [3]. In contrast to pro‑IL‑1β, pro-IL-1α is active, although cleavage dramatically enhances its bioactivity. IL-1β and IL-1α bind to the same receptor, IL-1R1, triggering the formation of the IL-1R1/IL-1R3/MyD88 complex. This induces signaling leading to the activation of the transcription factors NK-κB and AP-1 with the subsequent inflammatory response [4].
