WebPermeabilizing the cells through acetone or methanol fixation, or with the use of a detergent, allows antibodies to pass through the cellular membrane and enter the cell. The most common reagent used for cell permeabilization is non-ionic detergent, Triton X-100. Other milder permeabilizing agents include digitonin or related saponin compounds. WebCover slipping. Carefully remove the secondary antibody solution. Wash it with the TRIS buffered saline solution for 10 minutes with agitation. Repeat this step 2 more times until you have performed 3 washes. Carefully place the slice (right side up) on the slide and position it with a small brush. Apply mounting media and coverslip.
