Recombinant Human CD2 Protein

Product Name: Recombinant Human CD2 Protein
Catalog #:  HRP-0384
Manufacture:  LD Biopharma, Inc.

CD2 is a surface antigen of the human T-lymphocyte lineage that is expressed on all peripheral blood T cells. It is one of the earliest T-cell markers, being present on more than 95% of thymocytes; it is also found on some natural killer cells but not on B lymphocytes. Monoclonal antibodies directed against CD2 inhibit the formation of rosettes with sheep erythrocytes, indicating that CD2 is the erythrocyte receptor or is closely associated with it. Recombinant CD2 protein could be serviced as coating matrix protein for study human T cells expansion in vitro.

Full-length extracellular domain of human CD2 gene (25 - 209 aa) was constructed with 31 N-terminal T7/His tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified. Coating this recombinant protein at 1-10 ug / well (6 well plate) in T cell specific medium can be used for human T cell differentiation study in vitro.
