Mouse T1/ST2 (IL-33 R) monoclonal antibody (clone DJ8) for the identification and purification of murine T helper 2 (Th2) cells and all forms of murine mast cells.



T1/ST2 (also known as IL-1 R4 or IL-33Ra) is a transmembrane glycoprotein expressed on mast cells and Th2 cells. It is a selective marker for murine Th2 lymphocytes and plays a role in regulating inflammatory responses. IL-33 is a recently identified member of the IL-1 family of cytokines and is involved in Th2 mediated immune responses. IL-33 mediates its biological effects via T1/ST2 binding. The roles of IL-33 and T1/ST2 (IL-33Ra) have been investigated in many immune responses such as allergy, asthma, rheumatoid arthritis and osteoarthritis.



Rat anti-Mouse T1/ST2 purified mAb

Clone: DJ8


IgG Subclass: IgG1 (light chain not isotyped)


Form: The antibody is supplied in PBS, with 0.1% sodium azide as preservative and purified over protein G-sepharose. The characteristics of each lot are tested by FACS analysis with bone marrow derived mast cells.


Specificity: This clone recognizes the membrane anchored murine T1M protein on the surface of T helper 2 cells and mast cells. T1M appears on fetal blood derived mast cell progenitors before they express the Fce RI, on IL-3-dependent bone marrow derived mast cells and on mature peritoneal mast cells. The antibody detects T1S protein consisting only of the extracellular portion of the protein, which is secreted from growth factor and proinflammatory cytokine stimulated murine fibroblasts.


Immunogen: Eukariotically expressed fusion protein of mouse T1 ectodomain and human immunoglobulin Fc domain.
