T53-F1 immunostaining of primary spermatocyte nuclei of drosophilids. Note that in all species it is possible to recognize intranuclear structures specifically decorated by the antibody. For all species, the first image is a phase-contrast micrograph, the second shows the corresponding immunostaining. a-a': D. acanthoptera. b-b': D. americana. c-c': D. bifurca. d-d': D. funebris. e-e': D. littoralis. f-f': D. mauritiana. g-g': D. mercatorum. h-h': D. pseudoobscura. i-i': D. sechellia. j-j': D. tessieri. k-k': D. simulans. l-l': D. texana. m-m': D. yakuba.
