text: Cell surface molecule A5: a putative involvement in retinal central connection.
  We produced monoclonal antibodies against Xenopus tadpole visual centers and obtained an antibody named A5 (MAb-A5). The antigen of MAb-A5 is a cell-surface-related protein molecule (A5 antigen). Immunohistochemistry using MAb-A5 and an eye-transplantation experiment suggest the involvement of A5 antigen in specific cell recognition between retinal axons and their targets.
