Primary spermatocytes of mutants from Hackstein collection. a-c-e-g-i: phase contrast; b-d-f-h-j: immunofluorescence. a-b: wild type primary spermatocyte immunostained with the T53-1 antibody; note the prominent, threadlike kl-3 loop. c-d: wild type primary spermatocyte immunostained with the S5 antibody; the brightly fluorescent loop is kl-5, the dull fluorescent loop is ks-1. e-f: ms(2)HB108 spermatocytes exhibit a kl-3 loop which is only partially decorated by the T53-1 antibody. g-h: kl-3 phenotype in ms(2)HA30; the loop appears very reduced, although not as much as in ms(2)HB108. i-j: ms(2)HA10 meiocytes immunostained with anti α-tubulin antibody. Note that sperm tails grow from spermatocyte nuclei that have failed meiosis. Bar: 10 μm
