Fig. 2. Association of Rec8 with other cohesin proteins in the mouse. Testis
nuclear extracts were immunoprecipitated with either of three antibodies,
anti-Rec8, anti-SMC1 or anti-SMC3 antibody. The immunoprecipitates were
subjected to SDS-PAGE followed by western blotting with the same antibodies
plus anti-SCP3 antibody.
