简单介绍：
Interleukin1Receptor,TypeII(IL1R2)(AA14-343)(Active)protein(FcTag)
详情介绍：
Characteristics This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 64 kDa. The protein migrates as 68-74 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Purity >95 % as determined by SDS-PAGE.
Sterility 0.22 μm filtered
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
ProductDetails: Biological Activity Comment Biological Activity: Measured by its binding ability in a functional ELISA.Immobilized Biotinylated Human IL1a Protein (Cat# ILA-H8213) at 10 μg/mL (100 μL/well),can bind Recombinant Human IL1R2 /CD121b Protein,C-Fc Tag (Cat# IL2-H4256). The EC50 is typically 0.2-2 μg/mL.

SDS-PAGE: due to glycosylation.
Background Interleukin-1 receptor type 2 (IL1R2) is also known as CD121 antigen-like family member B (CDw121b), IL-1 type II receptor, Interleukin-1 receptor type II, belongs to the interleukin-1 receptor family. Two distinct types of IL1 receptors which are able to bind IL1 specifically have been identified, designated as IL1RI (IL1RA) and IL1RII (IL1RB). IL1R2 is non-signaling receptor for IL1A, IL1B and IL1RN, reduces IL1B activities. Serves as a decoy receptor by competetive binding to IL1B and preventing its binding to IL1R1. IL1R2 modulates cellular response through non-signaling association with IL1RAP after binding to IL1B. IL1R2 (membrane and secreted forms) preferentially binds IL1B and poorly IL1A and IL1RN. The secreted IL1R2 recruits secreted IL1RAP with high affinity, this complex formation may be the dominant mechanism for neutralization of IL1B by secreted/soluble receptors.
