Flow blot protocol• Collection of samples• Fixation of cells • Permeabilization of cells• Aliquot and incubate cells in incubation buffer• Incubation primary antibody 30-60 minutes• Washing of samples• Incubation secondary antibody 30 minutes (if
necessary)• Washing• Analyze cells on flow cytometric unit

In Cell Western / ELISA
• Coat plate with capture antibody (ELISA)• Incubate cells on plate (ICW)/grow cells (ELISA)• Fix cells (ICW)/ Add cell lysate to plate (ELISA)• Wash plates • Incubate cells with detection antibody• Wash plates• Add Fluorescent antibody (ICW)/ Add colour substrate
(ELISA)• Analyze on LICOR (ICW)/ Microtiter Plate Reader
