Hi Athanassios. Remove media, wash cells with PBS 2-3 times, fix with 3.7% paraformaldehyde for 10 minutes, and Wash the fixed cells 2-3 times with PBS. After washing, permeabilize the cell monolayer by adding 0.1% Triton X-100 in PBS and incubate for 15 minutes at 37 CÂ°.
Suspension cells can be centrifuged onto glass slides, bound to solid support using chemical linkers, or in some cases handled in suspension. The second step is to fix and permeabilize the cells, to ensure free access of the antibody to its antigen. Perfect fixation would immobilize the antigens, while retaining authentic cellular and subcellular architecture and permitting unhindered access of antibodies to all cells and subcellular compartments.
