Hep G2 cell line human has been used to study the cytotoxicity of carbon monoxide-releasing molecules and organic solvents on HepG2 cells and to evaluate the antiproliferative activity of aqueous extracellular polysaccharides (AEPS) for HepG2 using the MTT colorimetric assay. Study of hepatocyte function and specific protein expression.

Propidium iodide (PI) is a membrane impermeant dye that is generally excluded from viable cells. It binds to double stranded DNA by intercalating between base pairs. PI is excited at 488 nm and, with a relatively large Stokes shift, emits at a maximum wavelength of 617 nm. Because of these spectral characteristics, PI can be used in combination with other fluorochromes excited at 488 nm such as.The EC50 is the concentration of a drug that gives half-maximal response. The IC50 is the concentration of an inhibitor where the response (or binding) is reduced by half. Seems simple enough. But when you actually go to fit data to determine these values, there are several complexities and ambiguities. The rest of this article is about IC50 (I for inhibition, for downward sloping dose.The Bradford assay is based on the use of the dye Coomassie Brilliant Blue G-250, which is frequently abbreviated as Coomassie G-250 or Coomassie Blue. This is one of two Coomassie dyes that are often confused. Coomassie R-250 is used to stain protein gels but is not used in protein assays. In addition to being used in the Bradford assay, Coomassie G-250 can also be used to stain protein gels.
Antibiotic kill curve is a dose response experiment in which mammalian cells are subjected to increasing amounts of selection antibiotic to determine the minimum concentration of an antibiotic that can kill all the cells in a specific period of time. This is a crucial step before using a selection antibiotic to kill untransfected cells and generate stable cell lines. Since each mammalian cell.Cell culture preparation and plating protocol Related Video protocols library.
