Cytoplasmic extracts
WebProduct Description. The Cell Fractionation Kit is designed to provide a fast and efficient way of separating cultured cells into three distinct fractions: cytoplasmic, membrane/organelle, and nuclear/cytoskeletal. These … WebExtracts prepared from the isolated nuclei of cultured cells have been instrumental in dissecting the mechanisms by which transcription and mRNA processing occur. These extracts are able to recapitulate accurate transcription initiation and splicing in vitro, which has been useful in direct functional studies.

WebNote that nuclear, nucleoplasmic and chromatin fractions are 1/2 the volume of corresponding cytoplasmic extracts. This makes application in biochemical assays more convenient since the cytoplasm usually has 2-4x more total protein than the nucleus. For western blot analyses, be sure to load 1/2 the volume of nuclear versus cytoplasmic … WebJan 31, 2024 · Increased crowding in the cytoplasm to a high level was also reported to reduce the mobility of macromolecules and induce a liquid-to-glass transition in bacterial and yeast cytoplasm and Xenopus extracts (19–22). Thus, cells must tolerate some degree of cytoplasmic density changes but can respond to severe deviations from the …
