Anti-IL1R2 Antibody

Raised in rabbit and purified by affinity methods, this polyclonal reagent from Antibodies.com targets Interleukin-1 receptor type II (IL1R2, also known as CD121b, CDw121b, IL-1R-beta and IL1RB), a decoy receptor that sequesters IL-1α and IL-1β to attenuate inflammatory signalling. The IgG antibody is supplied as an unconjugated, liquid format at approximately 1 mg/mL in phosphate-buffered saline (PBS, pH ~7.3) containing 0.05% sodium azide as preservative, and is offered in a 50 µL trial aliquot for routine Western blot (WB) work. The reagent has been validated by the supplier for Western blotting on human and mouse samples, making it suitable for researchers examining IL-1 pathway regulation in inflammatory, immune-cell and oncology models where decoy-receptor biology is of interest. For long-term stability the vial should be stored refrigerated at 2–8 °C, with aliquoting recommended if extended use is planned; avoid repeated freeze–thaw cycles to preserve reactivity. Combined with standard HRP- or fluorescence-conjugated secondary antibodies, this polyclonal provides a reliable option for detecting endogenous IL1R2 levels across the species listed in the product specification.
