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. Identification of CD20 on human B cells associated with approximately 10% of peripheral blood lymphocytes.

Synonyms: CD2 FITC - CD20 PE

Source

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. CD20=Derived from the hybridization of mouse Sp2/0 myeloma cells with spleen cells from BALB/c mice immunized with the LB lymphoblastoid cell line.

Product

Product Form: Bi-Test (FITC/RPE) Reagent

Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide and 0.2% carrier protein

Purification Method: Protein A/G Chromatography
