Fixation cells
WebFixation can be done using crosslinking reagents such as paraformaldehyde. These are better at preserving cell structure but may reduce the antigenicity of some cell components as the crosslinking can obstruct antibody binding. Antigen retrieval techniques may be required, particularly if there is a long fixation incubation time or if a high ... WebFixation is one of the most critical steps in immunostaining. The object of fixation is to achieve good morphological preservation, while at the same time preserving antigenicity. …
