Ly-5 Antigen

Medical Condition:
Ly-5 Antigen

A group of lymphocyte surface antigens differentially located on subpopulations of mouse lymphocytes. This localization has been useful in distinguishing different functional subpopulations of lymphocytes. For example, cytotoxic T-cells bear primarily Lyt-23 on their surface and not Lyt-1, whereas helper cells bear Lyt-1 and not Lyt-23.
