Western blot analysis of extracts (35ug) from 9 different cell lines by using anti-PLK1 monoclonal antibody (HepG2: human; HeLa: human; SVT2: mouse; A549: human; COS7: monkey; Jurkat: human; MDCK: canine; PC12: rat; MCF7: human) (1:200).
HEK293T cells transfected with either RC201795 overexpress plasmid (Red) or empty vector control plasmid (Blue) were immunostained by anti-PLK1 antibody (TA500383), and then analyzed by flow cytometry.
Immunoprecipitation (IP) of PLK1 by using TrueMab monoclonal anti-PLK1 antibodies (Negative control: IP without adding anti-PLK1 antibody.). For each experiment, 500ul of DDK tagged PLK1 overexpression lysates (at 1:5 dilution with HEK293T lysate), 2ug of anti-PLK1 antibody and 20ul (0.1mg) of goat anti-mouse conjugated magnetic beads were mixed and incubated overnight. After extensive wash to remove any non-specific binding, the immuno-precipitated products were analyzed with rabbit anti-DDK polyclonal antibody.
HEK293T cells were transfected with the pCMV6-ENTRY control (Left lane) or pCMV6-ENTRY PLK1 (RC201795, Right lane) cDNA for 48 hrs and lysed. Equivalent amounts of cell lysates (5 ug per lane) were separated by SDS-PAGE and immunoblotted with anti-PLK1. (1:. Positive lysates LY417592 (100ug) and LC417592 (20ug) can be purchased separately from OriGene.
