T Cell Receptor / TCR gamma/delta Mouse Monoclonal Antibody [Clone ID: TCR1]

Specifications

Product Data
Clone Name	TCR1
Applications	FC
Recommended Dilution	Flow Cytometry: < / = 0.2 µg/10e6 cells. (Ref.1-3)
Reactivities	Chicken
Host	Mouse
Isotype	IgG1
Clonality	Monoclonal
Specificity	This antibody recognizes TCR gamma/delta. It precipitates a heterodimer of Mr 90-kDa (two bands of Mr 40-kDa and 50-kDa upon reduction) on Chicken peripheral blood T cells. (Ref.1,2) Deglycosylation of the heterodimer yields two polypeptides of Mr 35-kDa and 32-kDa from TCR1 precipitates.

Concentration	lot specific
Conjugation	PE
Storage	Store the antibody undiluted at 2-8°C. DO NOT FREEZE! This product is photosensitive and should be protected from light. Avoid repeated freezing and thawing.
Stability	Shelf life: one year from despatch.
Background	T cell receptors (TCR) recognize foreign antigens which have been processed as small peptides and bound to major histocompatibility complex (MHC) molecules at the surface of antigen presenting cells (APC). Each T cell receptor is a dimer consisting of one alpha and one beta chain or one delta and one gamma chain. Unlike human and mouse, in which gamma/delta cells comprise a minor subset of T lymphocytes in the circulation, the chicken has a relatively large subset of gamma/delta T cells. The frequency of TCR gamma/delta cells is usually 20-25% of the total blood T cells, but may reach approximately 50% in chickens of 6 months of age. The majority of TCRgamma/delta+ cells in the thymus and blood are CD4-CD8-, although a small subset of them may express CD8 or CD4 coreceptors. However, when the TCRgamma/delta+ cells migrate into the spleen and intestine, most of them begin to express CD8. Although the biological function of gamma/delta T cells is unclear, they are clearly capable of cytotoxic activity in vitro. The CD8+ gamma/delta T cells may also be involved in down-regulation of the immune response. They cannot, however, induce a graft-vs-host (GVH) reactions.ociates with CD3 and is expressed on a T cell subset found in the thymus, the intestinal epithelium, and the peripheral lymphoid tissues and peritoneum. Most gamma/delta T cells are CD4-/CD8-, some are CD8+. T cells expressing the gamma/delta TCR have been shown to play a role in oral tolerance, tumor-associated tolerance, and autoimmune disease.
