Anti-IL37 Antibody

This polyclonal reagent from Antibodies.com enables western blot detection of IL-37 (interleukin-37, also known as IL-1F7), an anti-inflammatory member of the IL-1 cytokine family that suppresses innate immune signaling through SMAD3-dependent mechanisms. Raised in rabbit and supplied at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, the antibody is provided as a 100 µl volume in liquid form for direct dilution into standard immunoblotting workflows. Cross-reactivity with human, mouse, and rat samples has been validated, supporting studies of cytokine biology, inflammatory disease models, and the tumor-suppressive role of IL-37 in cancer research. The unconjugated format leaves labeling choices open, allowing laboratories to pair the reagent with HRP, biotin, or fluorescent secondary reagents of their choice. Storage at -20°C in the glycerol-stabilized buffer preserves activity across repeated freeze-thaw cycles, and the sodium azide additive prevents microbial contamination during routine bench handling.
