T cell receptors

Patent Granted The T cell receptor or TCR is a molecule found on the surface of T lymphocytes (or T cells)[1] that is responsible for recognizing antigens bound to major histocompatibility complex (MHC) molecules. The binding between TCR and antigen is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen and many antigens are recognized by the same TCR.
