Chitosan-mediated synthesis of biogenic silver nanoparticles (AgNPs), nanoparticle characterisation and in vitro assessment of anticancer activity in human hepatocellular carcinoma HepG2 cells.
The biopolymer chitosan is at present in widespread use due to its nontoxicity, biocompatibility and biodegradability. Subsequently, on this examine, chitosan extracted from shrimp shells was used to synthesise biogenic silver nanoparticles (AgNPs). UV-visible spectrophotometry of lowered silver nanoparticles within the colloidal answer confirmed a single peak at 400 nm, confirming the formation of AgNPs.…Read More
Tyrosine hydroxylase has been purified to homogeneity from cultured PC-12 cells. The protein migrates as a single band with a molecular weight of 60,000 on sodium dodecyl sulfate polyacrylamide electrophoresis. Two-dimensional electrophoresis of the pure enzyme resolves three spots (every with molecular weights of 60,000) with isoelectric factors of 5.4, 5.Eight and 5.9. This cost…Read More
