Deoxycytidine kinase(DCK) immunoprecipitated from H460cells with 7.5ug (microgram) of the dCK antibody using the Pierce classic mammalian IP kit (#45217) reagent as described as manufacturer instructions (lane 1, 3) and Current Protocols in Cell Biology, 1998, 7.2.1-7.2.21. Proteins separated on a 12% SDS gel, transferred to a PVDF membrane and probed with 1:700 dilution of DCK antibody. Bands were detected using enhanced chemiluminescence (SuperSignal West Pico Chemiluminescent Substrate Kit). No specific reagents were employed to remove IgG from immunoprecipitated sample.
