Product Specifications

Product Specific Information

The B20.6 monoclonal antibody reacts with the mouse T-cell receptor (TCR) V beta 2 chain.
Neonatal T cells expressing V beta 2 and exposed to the Balb/cV virus are eliminated during negative selection, while adult T cells expressing V beta 2 and exposed to the same virus are clonally expanded.

Applications Reported: Flow cytometric analysis
Applications Tested: Tested by flow cytometric analysis of lymph node cells. Recommended ≤1 µg per test.
A test is defined as the amount of antibody that stains a cell sample in 100 µL final volume. Cell number may range from 10^5 to 10^8 cells/test.
Careful titration is advised for optimal assay performance.

Fluorescence Properties:

• Excitation: 488 nm
• Emission: 520 nm
• Laser: Blue Laser
• Filtration: 0.2 µm post-manufacturing filtered

Target Information

T cell receptors (TCR) discriminate foreign from self-peptides presented by MHC class II molecules, critical for adaptive immune response.
Recognition of self-peptides is linked to autoimmune diseases, and mutant self-peptides are associated with tumors.
Superantigen engagement of TCRs can cause toxic shock syndrome.
Autoantibodies to V beta segments have been found in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), potentially modulating inflammatory reactions.

Most human T cells express TCR alpha-beta and either CD4 or CD8 (single positive).
A small fraction lacks both (double negative), and increased alpha-beta DN T cells are observed in autoimmune and immunodeficiency disorders.
Gamma-delta T cells, mainly in epithelium, exhibit less diversity and distinct antigen recognition, with subsets showing antitumor and immunoregulatory activity.
