Western blot analysis of extracts from 293T cells, mock-transfected (-) or transfected with a construct expressing Cre recombinase (+), using Cre Recombinase (D3U7F) Rabbit mAb (upper) and β-Actin (13E5) Rabbit mAb #4970 (lower).
Confocal immunofluorescent analysis of ER-Cre-MEF cells, untreated (left) or treated with 4OH-Tamoxifen (200 ng/ml; center), and Cre-transfected 293 cells (right), using Cre Recombinase (D3U7F) Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5 ® #4084 (fluorescent DNA dye). The ER-Cre-MEF cells were kindly provided by Dr. Mark Bedford (M.D. Anderson Cancer Center, TX).
Flow cytometric analysis of COS-7 cells, untransfected (blue) or transfected with Cre recombinase (green), using Cre Recombinase (D3U7F) Rabbit mAb. Anti-rabbit IgG (H+L), F(ab') 2 Fragment (Alexa Fluor ® 647 Conjugate) #4414 was used as a secondary antibody.
