|0.5 mg/mL of rabbit anti-IL1R2 monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating|
|0.5 mg/mL mouse anti-IL1R2 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 1.0 μg/mL in detection antibody dilution buffer before use|
|Each vial contains 24 ng of recombinant IL1R2. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 600 pg/mL is recommended.|
|The minimum detectable dose of human IL1R2 (IL1RB / CD121b) was determined to be approximately 9.375 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard|
The human IL1R2 (IL1RB / CD121b) ELISA Pair Set is for the quantitative determinationof human IL1R2.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for IL1R2(IL1RB / CD121b) coated on a 96-well plate. Standards andsamples are added to the wells, and any IL1R2 ( IL1RB / CD121b) present binds tothe immobilized antibody. The wells are washed and a horseradish peroxidaseconjugated mouse anti-IL1R2 monoclonal antibody is then added, producing anantibody-antigen-antibody "sandwich". The wells are again washed and TMBsubstrate solution is loaded, which produces color in proportion to the amountof IL1R2 present in the sample. To end the enzyme reaction, the stop solutionis added and absorbances of the microwell are read at 450 nm.

Interleukin 1 receptor, type II (IL1R2) also known as CD121b (Cluster of Differentiation 121b) is a cytokine receptor that belongs to the interleukin-1 receptor family. This protein binds interleukin alpha (IL1A), interleukin beta (IL1B), and interleukin 1 receptor, type I (IL1R1/IL1RA), and acts as a decoy receptor that inhibits the activity of its ligands. The pleiotropic cytokine IL1 is produced to regulate development and maintenance of the inflammatory responses, and binds to specific plasma membrane receptors on cells. Two distinct types of IL1 receptors which are able to bind IL1 specifically have been identified, designated as IL1RI (IL1RA) and IL1RII (IL1RB). IL1R1 contributes to IL-1 signaling, whereas the IL-1R2/CD121b has no signaling property and acts as a decoy for IL-1. IL-1R2/CD121b structurally consisting of a ligand binding portion comprised of three Ig-like domains, a single transmembrane region, and a short cytoplasmic domain, is expressed in a variety of cell types including B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. Interleukin 4 (IL4) is reported to antagonize the activity of interleukin 1 by inducing the expression and release of this cytokine.
