Active Recombinant Human IL1RN protein, His-tagged

• Cat.No.: IL1RN-51H
• Product Overview: Active Recombinant Human IL1RN protein(P18510)(26~177 aa), fused with N-terminal His tag, was expressed in E.coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 26-177 aa
• Form: Lyophilized from sterile 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
• Bio-activity: IL1RA (interleukin-1 receptor antagonist) is an agent that binds to the cell surface interleukin-1 receptor (IL-1R), which would prevent IL-1 from intracellular signal transduction. Thus, a binding ELISA assay was constructed to detect the association of recombinant human IL1RA with recombinant human IL1R1. Briefly, IL1RA were diluted serially in PBS with 0.1% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to IL1R1-coated microtiter wells and incubated for 2h at 37°C. Wells were washed with PBST and incubated for 1h with anti-IL1RA pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37°C. Finally, add 50µL stop solution to the wells and read at 450nm immediately. The binding activity of IL1RA with IL1R1 was shown and this effect was in a dose dependent manner.
