Alternatively, remove formaldehyde … WebTriton, digitonin and saponin are examples of permeabilization reagents which act by disrupting the cellular membrane. The level of permeabilization is important as epitopes access may require different levels of permeabilization (e.g. cytoplasmic vs nuclear epitopes) and unbound antibody has to be sufficiently washed out of the cells.
