Description

Description

Description: The RMST2-33 monoclonal antibody reacts with mouse ST2, also known as IL-33R or interleukin 1 receptor-like 1. ST2 is a member of the IL-1 receptor family. In the membrane-bound form, it consists of three extracellular immunoglobulin domains and an intracellular toll-interleukin-1 receptor domain. ST2 forms a dimer with IL-1R accessory protein in a ligand-dependent manner. IL-33/ST2 interaction induces the production of TH2 cytokines. ST2 also has a soluble isoform lacking transmembrane and intracellular toll-interleukin-1 receptor domains. It is believed that the soluble form functions as a decoy receptor that can block membrane bound IL-33/ST2 interaction. ST2 is expressed by TH2 lymphocytes, mast cells, eosinophils, basophils, innate lymphocytes, smooth muscle cells, and endothelial cells and is involved in host defense, allergy, and inflammation. IL-33/ST2 interaction has also been shown to be atheroprotective. RMST2-33 has been reported to bind and activate ST2 in in vitro assays. Applications Reported: This RMST2-33 antibody has been reported for use in functional assays and flow cytometric analysis. Functional activity has been determined by the ability to induce IL-6 production in mouse bone marrow-derived mast cells when used between 1-10 µg/mL. Applications Tested: This RMST2-33 antibody has been tested by flow cytometric analysis of bone marrow-derived mast cells. This can be used at less than or equal to 0.5 µg per test.

A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay. Storage and handling: Use in a sterile environment. Filtration: 0.2 µm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC. ST2 is a member of the interleukin 1 receptor family. Studies of ST2 in mouse suggested that this receptor can be induced by proinflammatory stimuli, and may be involved in the function of helper T cells. ST2 belongs to the interleukin-1 receptor family with three Ig-like C2-type (immunoglobulin-like) domains and a TIR domain. ST2 is a receptor for interleukin-33 (IL-33) which upon stimulation recruits the signaling molecules MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. Reports also suggest its possible role in helper T-cell function as well as in cell growth. Three isoforms of ST2 have been reported where isoform C is a membrane form and isoform B is a secreted form. ST2 may be induced by proinflammatory stimuli, and may also be found in serum of autoimmune disease. Different isoforms are restricted to different tissues while high expression of this protein is evident in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine.
