Arrest of cell membrane movements by in vitro incubation with polycation reversed by polyanion.
نویسندگان
چکیده
A total arrest of cell membrane movement occurred after incubation for 2 h of cultured fibroblasts with the polycation DEAE-dextran. The immobilized cells resumed normal membrane undulations after exposure for 5 min to the polyanion dextran-sulphate. The influence of DEAE-dextran on the electrophoretic mobility, which was seen after 10 min of incubation was also erased by a subsequent incubation with dextran-sulphate. No influence on growth of the culture was seen.

Linear water-soluble polyelectrolytes, i.e., poly(methacrylate) polyanion and poly(N-ethyl-4-vinylpyridinium) polycation, were used as carriers for the reactants in immunoassay. The strength of ionic forces through distance and the cooperative binding of oppositely charged chains, the carriers interact with each other at an extremely high rate and affinity. These properties of the polyelectroly...
متن کاملInfluence of the polyanion on the physico-chemical properties and biological activities of polyanion/DNA/polycation ternary polyplexes.
It was recently reported that polyanion/DNA/polycation ternary polyplexes markedly improve gene transfection activity in comparison with the original DNA/polycation binary polyplexes. In this study to explore the influence of the polyanion on the physico-chemical properties and biological activity of polyanion/pDNA/polycation ternary polyplexes four types of biocompatible polyanions were select...

Dendrostellera lessertii (Thymelaeaceae) is a toxic plant that grows in parts of Iran. The anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-HK), have been established using several cancer cell lines. Methods: In a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...
