Product Information
KE00288 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Human IL-1R2 ELISA kit is to be used to detect and quantify protein levels of endogenous IL-1R2. The assay recognizes human IL-1R2. An antibody specific for IL-1R2 has been pre-coated onto the microwells. The IL-1R2 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human IL-1R2 is added to detect the captured human IL-1R2 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Interleukin-1 receptor type 2 (IL-1R2, also known as CD121b) is a cytokine receptor that belongs to the interleukin 1 receptor family. IL-1R2 binds interleukin alpha (IL-1A), interleukin beta (IL-1B), and interleukin 1 receptor, type I (IL-1R1/IL-1RA), and acts as a decoy receptor that inhibits the activity of its ligands. It exists in both a membrane bound and soluble form. Soluble molecules are found in cell culture supernatant and in biological fluids under several physiopathological conditions.

FAQ
1、I have limited sample diluent. How should I handle samples requiring high dilution factors?
Answer: We recommend performing a serial dilution. For example, if human serum requires a 1,000,000-fold dilution, you can use a three-step 100× dilution method as follows:
Step 1: Take 2 uL of human serum and add it to 198 uL of sample diluent, mix thoroughly to obtain a 100-fold diluted sample.
Step 2: Take 2 uL of the 100-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 10,000-fold diluted sample.
Step 3: Take 2 uL of the 10,000-fold diluted sample and add it to 198 uL of sample diluent, mix thoroughly to obtain a 1,000,000-fold diluted sample.
If further dilution is required, additional serial steps can be used. We do not recommend using any other solutions or water for dilution, except for the sample diluent we suggest. If your sample diluent is still insufficient, please contact our customer service for more sample diluent.
