Web11 aug. 2024 · Fixing limitations: An scRNA-seq protocol for fixed tissues. “We want to be able to store these tumor samples and run them when we know which ones are the most interesting.” –Translational researcher. “A lot of times, samples don’t even arrive until 4 or 5 PM. Those projects are really hard on our staff.” –Director of a Core Lab. In both immersion and perfusion fixation processes, chemical fixatives are used to preserve structures in a state (both chemically and structurally) as close to living tissue as possible. This requires a chemical fixative. Crosslinking fixatives act by creating covalent chemical bonds between proteins in tissue. This anchors soluble proteins to the cytoskeleton, and lends additional rigidity to the tissue. Preservat…
