WebFixation cross-links macro-molecules in the cells and locks the target proteins in place, and permeabilization allows antibodies to access the intracellular space. This video goes over some of the considerations to keep in mind when choosing or testing reagents for fixation and permeabilization for your flow cytometry protocol. WebThis protocol provides general instructions for fixation, permeabilization, and blocking to prepare your cells for immunolabeling. Fixing and permeabilizing cells generally locks them in place and makes it possible for larger molecules such as antibodies to access the interior of the cell. Download this protocol
