From: Cohesin loading factor Nipbl localizes to chromosome axes during mammalian meiotic prophase

Nipbl is expressed in mouse spermatocytes. (A) Western blotting assays on total protein extracts from whole mouse testis (Tes) and mouse pre-B cell line (B3) [22] using antibodies against Nipbl. Anti-Lamin B1 was used as a loading control for each blot. (B) Immunohistochemistry on seminiferous tubule cross-sections from wild-type testis with (left) or without (right) the primary antibody KT55. Nuclei were counterstained with hematoxylin. G, spermatogonium; C, spermatocyte; R, round spermatid; Z, spermatozoon; S, Sertoli cell. Scale bar 200 μm.
