WebJul 9, 2016 · It is followed by permeabilization (i.e., punching holes in the cell membrane) to allow entry of antibodies inside the cell to bind and detect the protein. Always fix the cells first and then permeabilize the cells—otherwise the contents of the permeabilized cells might leak out and result in loss of your protein of interest. WebCell permeabilization leads to the leakage of cytosolic proteins out of the cell. Adding back cytosolic proteins to the permeabilized cells and measuring exocytosis provides a mechanism by which proteins involved in exocytosis can be identified (Baker and Knight, 1981; Sarafian et al., 1987).
