Background: Identification of human T cells and subset of NK cells associated with the receptor for sheep erythocytes rosettes expressing the 45-50,000 M.W. surface antigen. Identification of human T lymphocytes in multiple stages of T cell development, including a major subset of mature peripheral T cell. CD7 antigen is often increased on T leukemic cells. The CD7 molecule is a 40,000 M.W. surface antigen that is expressed on T-Lymphoid and myeloid precursors in fetal liver and bone marrow.
Immunogen: CD2=Derived from the hybridization of mouse Sp2/0 myeloma cells with spleen cells from BALB/c mice immunized with t lymphocytes activated by mixed lymphocyte culture. CD7=Derived from the hybridization of mouse P3-X63-Ag8.653 myeloma cells with spleen cells of BALB/c mice immunized with T-acute lymphoblastic leukemia (T-ALL) cells.
Purification Method: Protein A/G Chromatography
Concentration: Titered for flow cytometry
Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide and 0.2% carrier protein
