Identification of the SIRT1 interacting proteins during initiation phase of reprogramming. (A) 2° MEFs containing DOX inducible MKOS was sorted out by FACS according to the FITC gating indicated by circle dash line. (B) co-immunoprecipitation assay using SIRT1 antibody or rabbit IgG followed by Western blotting analysis (IB) using antibodies against SIRT1, KU70 and WRN.
