title: Anti-lamprey retinal antibodies: immunohistochemistry on the retinas of several species of vertebrates.
abstract: Two monoclonal antibodies, H16 and B11, which were raised against lamprey retinal homogenate, were found to react with both short and long photoreceptor outer segments. On Western blotting of the retinal homogenate, both antibodies recognized a 40,000 Da and a 80,000 Da band. H16 antibody stained rod outer segments of all examined vertebrates, all cone outer segments of the turtle and chicken, and certain cone outer segments of the macaque. B11 antibody stained submammalian rod outer segments and some mammalian cone outer segments, leaving all mammalian rod outer segments unstained. The epitope recognized by H16 antibody is considered to be located in a conserved or commonly inherited element of an outer segment-bound molecule, presumably rhodopsin. B11 antibody, on the other hand, seems to recognize a reactive group which has failed to be inherited by mammalian rod cells; why it recognizes all cone outer segments in the turtle and chicken and only a part of them in the cow, cat, and macaque, meanwhile ignoring all of them in the frog and fish, is subject to further study.
