A. Flowchart of the experimental design. B. Strain YIO81 with plasmid pRS406 (pGAL URA3), pIO88 (pGAL-SCC3 URA3) or pIO88R1 (pGAL-scc3-I358ins URA3) were grown in YEP lactic acid (2%) to mid-log phase and arrested in G1 using α-factor. Galactose was added to a final concentration of 2% for 1 h; cells were then released into the cell cycle and rearrested in G2/M by nocodazole. Sister chromatid cohesion was analyzed by using the GFP spot assay (n = 3). C. Strains analyzed in B were processed for chromatin spreads after cells were arrested in G2/M, as described in the materials and methods section. Cohesin was detected by indirect immunofluorescence with an anti-Mcd1 antibody (n = 2).
