I would like an antibody to any protein that is expressed in primary spermatocytes, and not in any post-meiotic stages, other than b2tubulin which I cant use. It is also important that the marker is not expressed in the sheath cells. It would be useful if this protein has nothing to do with cell cycle progression. If anyone has such an antibody, or has any suggestions about suitable proteins, I look forward to hearing from you! Helen .
