WebApr 12, 2024 · In summary, fixation is the first stage of a successful IHC protocol. If the cells or tissues to be preserved are subject to artifacts as a result of inadequate or careless fixation, then the morphological results obtained during the IHC experiment will suffer, and conclusions drawn from antibody staining may be incorrect. WebExcept where noted in the protocol, all staining should be done on ice or at 4°C with minimal exposure to light. The fixation and permeabilization steps that are required for the detection of intracellular antigens may alter the light scatter properties of cells and may increase non-specific background staining.
