摘要：

An enhanced immunohistochemical procedure to detect proliferating cell nuclear antigen (PCNA), an endogenous cell replication marker, has been successfully applied to formalin-fixed, paraffin-embedded archival rat and mouse tissues. The procedure involves microwave oven heating of tissue sections in a commercially available antigen retrieval solution of heavy metal salts. Successful immunohistochemical staining of PCNA can be consistently obtained in tissues fixed for over 24 months in formalin and in sections made from paraffin blocks stored in our tissue archives for up to 19 months. Use of this technique will allow retrospective staining of rodent tissues for identification of S phase cells as an indication of DNA replicative activity in previously conducted toxicity and carcinogenicity studies.
