- Not recommendedLearn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.Antigen retrieval on frozen tissue is not recommended. The retrieval process can be too harsh and damage the tissue. However, it is often recommended to restore antigenicity in formalin-fixed tissues.www.bio-techne.com/imaging/immunohistochemist…The absence of a formaldehyde based fixative eliminates the need for an antigen retrieval step. However, if frozen tissue or cytological specimens have been fixed in formalin, antigen retrieval can be attempted, although the friable nature of the specimens, in particular brain tissue, may compromise the success.docs.abcam.com/pdf/protocols/IMMUNOHISTOCH…
