Short Description: This IL-1 Beta Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in rat cell culture supernatant, serum and plasma (EDTA, citrate, heparin).
Storage Instruction: If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual.
Assay Time: 3.5h
Detection: Colormetric
Gene Symbol: Il1bUniprot ID=IL1B_RAT"
Specificity: This kit recognizes Rat IL-1 Beta in samples.No significant cross-reactivity or interference between Rat IL-1 Beta and analogues was observed
Sample Type: serum, plasma and other biological fluids
Function Potent pro-inflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells. Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells. Plays a role in angiogenesis by inducing VEGF production synergistically with TNF and IL6. Involved in transduction of inflammation downstream of pyroptosis: its mature form is specifically released in the extracellular milieu by passing through the gasdermin-D (GSDMD) pore.
Protein Name Interleukin-1 Beta
Il-1 Beta
Cellular Localisation Cytoplasm
Cytosol
Secreted
Lysosome
Extracellular Exosome
The Precursor Is Cytosolic
In Response To Inflammasome-Activating Signals
Such As Atp For Nlrp3 Inflammasome Or Bacterial Flagellin For Nlrc4 Inflammasome
Cleaved And Secreted
Mature Form Is Secreted And Released In The Extracellular Milieu By Passing Through The Gasdermin-D (Gsdmd) Pore
In Contrast
The Precursor Form Is Not Released
Due To The Presence Of An Acidic Region That Is Proteolytically Removed By Casp1 During Maturation
The Secretion Is Dependent On Protein Unfolding And Facilitated By The Cargo Receptor Tmed10
Alternative ELISA Names Interleukin-1 Beta ELISA kit
Il-1 Beta ELISA kit
Il1b ELISA kit
Specificity This kit recognizes Rat IL-1β in samples. No significant cross-reactivity or interference between Rat IL-1β and analogues was observed.
Reproducibility Both intra-CV and inter-CV are
