Application Differences Among Glutaraldehyde, Paraformaldehyde, and Formalin in Tissue and Cell Sample Fixation
Fixation is a critical pretreatment step in histology, cytology, immunostaining, and ultrastructural observation. Its core purpose is to preserve the in situ morphology, molecular localization, and structural stability of samples as much as possible. Glutaraldehyde, paraformaldehyde, and ...
Comparison of Low-pH, High-pH, and Enzymatic Antigen Retrieval Systems in IHC
Antigen retrieval in IHC determines the extent to which epitopes masked after fixation can be re-exposed, and it directly affects localization quality, signal intensity, and tissue integrity.
Immunohistochemistry (IHC) staining antigen retrieval protocol
Most formalin-fixed tissues require an antigen retrieval step before immunohistochemical staining. Methylene bridges formed during fixation cross-link proteins and mask antigenic sites. Antigen retrieval methods break these methylene bridges and expose antigenic sites, allowing antibodies to ...
