Embedding tissue processing
WebEssentially there are three methods of processing tissue to prepare tissue sections: paraffin embedding, resin embedding, and the use of frozen (cryostat) sections. Preston et al. ( 12) have outlined many of the pros and cons concerning these techniques (all of which are routinely used in laboratories working on tissue organization and pathology). WebSamples are collected in the field, or the mechanical processing of fresh samples is insufficient for thorough disruption. While freezing allows the researcher to postpone DNA/RNA/protein isolation, it is time ... Embedding frozen tissue is similar as embedding unfrozen tissue, except that you must freeze down the frozen tissue in OCT compound ...
