background CD2 which is also known as E-rosette receptor, T11 and lymphocytefunction antigen-2 (LFA-2) is expressed on T cells, thymocytes, and subset of natural killer cells. Human CD2 functions as the receptor for sheep erythrocytes, human CD58 (LFA-3), and CD15s (Sialyl Lewis X). p56lck, p59fyn, CD3eta and CD3epsilon are tyrosine-phosphorylated after CD2 stimulation. CD2 plays a role in T cell activation, T- or NK-cell-mediated cytolysis, apoptosis in activated peripheral T cells, and regulation of T cell anergy.
description CD2 Human Recombinant expressed in E.Coli is a single, non-glycosylated polypeptide chain containing 209a.a. (25-209 a.a) and having a molecular weight of 23.8kDa.CD2 is fused to a 24a.a. His-tag at N-terminus and purified by unique purification methods.
