Background
Identification of CD4 on human helper/inducer T cells expressing the 60,000 M.W. surface antigen (HLA class II reactive). CD4 is present in low density on monocytes. Identification of CD8 on human T cells suppressor/cytotoxic expressing the 32,000 M.W. alpha subunit surface antigens.

Synonyms: CD4 FITC - CD8 PE

Source

Immunogen: CD4=Derived from the hybridization of mouse NS-1 myeloma cells with spleen cells from BALB/c mice immunized with human perherial blood T lymphocytes. CD8=Derived from the hybridization of mouse NS-1 myeloma cells with spleen cells from BALB/c mice immunized with human perherial blood T lymphocytes.

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
