A method is disclosed for reversing fixation-induced cross-linking in tissue specimens that have been preserved for histological examination. The method involves placing the fixed tissue in a liquid under elevated temperature and pressure conditions that are sufficient to reverse the fixation-induced cross-linking, restore antigenicity to proteins, and permit improved molecular and proteomic analysis of the preserved tissue specimen. Methods are also disclosed for processing tissues for histological examination under elevated pressure conditions that enhance the perfusion of liquid reagents into the tissue and reduce overall processing times.

Immunoliposomes and use thereof in highly specific and sensitive nucleic acid amplification assays relying on amplification of specific nucleic acid sequences released from encapsulation within a liposome after a receptor on the liposome couples with a targeted analyte/antigen immobilized on a select surface. The immunoliposome nucleic acid amplification assay permits both quantitative and qualitative analyte detection.
