The pGEM-T is 3kb in length, and contains the amplicin resistance gene, conferring selection of the plasmid in E. coli, and the ori site which is the bacterial origin of replication. The plasmid has multiple cloning sites as shown below. The coding sequence was inserted by TA cloning. Many E. coli strains are suitable for the propagation of this vector including JM109, DH5α and TOP10.
The coding sequence can be easily obtained by digesting the vector with proper restriction enzyme(s). The coding sequence can also be amplified by PCR with M13 primers, or primer pair SP6 and T7.

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.
