The mouse monoclonal antibody 11F2 recognizes an extracellular epitope in all molecular forms of the TCR gamma/delta.
Purification
Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μL reagent / 100 μL of whole blood or 106 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.
The antigen-specific T cell receptor (TCR) is composed of either alpha and beta subunit, or gamma and delta subunit. Majority of T cells present in the blood, lymph and secondary lymphoid organs express TCR alpha/beta heterodimers, whereas the T cells expressing TCR gamma/delta heterodimers are localized mainly in epithelial tissues and at the sites of infection. The subunits of TCR heterodimers are covalently bonded and in the endoplasmic reticulum they associate with CD3 subunits to form functional TCR-CD3 complex. Lack of expression of any of the chains is sufficient to stop cell surface expression.,TCRG/D
