WebAbstract. Freeze-substitution (FS) is to replace ice crystals with organic solvent containing fixatives and finally embed frozen tissue samples in synthetic resin or paraffin, showing morphology of cells and tissues at the time of freezing. This FS fixation usually leaves frozen tissues in the organic solvent with fixatives maintained below the ... WebNov 14, 2014 · 3.6 Freeze Substitution Without Automation of Liquid Exchange. Freeze substitution without automation of liquid exchange (e.g., Leica FSP or RMC FS-8500) or a fully manual “home-built system” requiring basic laboratory tools: a platform shaker, LN, a metal block with holes for cryotubes, and an insulated container such as an ice bucket . 1. brittany e johnson md
