The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions. The solution is free of unconjugated biotin.
Concentration:
0.5 mg/ml
Storage & Handling:
The antibody solution should be stored undiluted at 4°C. Do not freeze.
Each lot of this antibody is quality control tested by ELISA assay. For ELISA capture applications, a concentration range of 0.5-2 μg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes:
ELISA Detection: The biotinylated Poly5095 antibody is useful as the detection antibody in a sandwich ELISA assay, when used in conjunction with the purified JK1RA-1 (Cat. No. 509902) antibody as the capture antibody.
Interleukin-1 receptor antagonist (IL-1RA) is composed of three isoforms, one secreted (sIL-1Rα/IL-1Rα1), two intracellular (IL-1Rα2/IL-1Rα3) and produced by monocytes, tissue macrophages, Langerhans cells, dendritic cells, T and B cells, natural killer (NK) cells, large granular lymphocytes (LGL), vascular endothelium, smooth muscle, fibroblasts, thymic epithelia, astrocytes, microglia, glioma cells, keratinocytes, and chondrocytes. It is upregulated by IL-1β, IL-4, IL-6 and downregulated by glucocorticoids. The Poly5095 polyclonal antibody reacts with human interleukin-1 receptor antagonist (IL-1RA).
