Description

Immunogen

human thymocytes followed by peripheral blood T cells.

Antigen Background

CD8 is a two chain complex (α/α, α/β) receptor for Class I MHC molecules. The receptor′s cytoplasmic portion is associated with p56lck protein tyrosine kinase which phosphorylates nearby proteins. The antigen is strongly expressed on approximately one third of mature T cells (cytotoxic/suppressor T cells).

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Specificity

Recognizes the CD8 human T cytotoxic/suppressor lymphocyte cell surface glycoprotein. Approximately 90% of thymocytes are stained in suspension. In thymus sections, both cortical and medullary thymocytes are stained. A subset of NK cells express this antigen weakly. The epitope recognized by this clone is sensitive to routine formalin fixation and paraffin embedding.
3rd Workshop: code no. 567

Preparation Note

Quantum Red is a tandem fluorescent dye created by coupling R-phycoerythrin with Cy5 reactive dye. This red dye is efficiently excited at 488 nm and emits at 670 nm.
