Anti-GL7 antibodies are immunological tools used to detect the epitope marker originally identified in mouse T and B cells. The GL7 epitope is now known to be expressed in a number of cell populations, including activated B cells in germinal centers in the spleen and lymph nodes, thymocytes, and some neuronal cells. GL7 plays a role in the development and maturation of B cells. Its expression is highest in immature B cells, decreasing as maturation occurs. It can also be used as an activation marker for T and B cells. GL7 antibodies can be used for immunohistochemistry, flow cytometry, Western blot, and ELISA kits.
