Figure 1. Sorting and validating replicative senescent yeast cells.

a. Biotin-Streptavidin method for sorting senescent cells was performed as depicted. b. A comparison of bud scars on adsorbed and not adsorbed yeast cells stained by Solophenyl Flavine 7GFE 500%. c. Yeast cells were cultured for 48 hours and then divided into three groups: no-sorting, adsorbed by magnets and those not adsorbed by magnets. The bud scars for a hundred cells were counted. The average number of bud scars on the adsorbed cells was approximately three times the figures obtained for not-adsorbed cells.
