Interaction of Surface-active Agents with Macromolecules

INTERACTION OF DNA WITH THE FOLDED AND UNFOLDED HISTONE HI IN THE PRESENCE OF SURFACE ACTIVE AGENTS

Interaction between DNA and histone H, was investigated in the presence and absence of sodium-n-dodecyl sulphate (SDS) and dodecyl trimethylammonium bromide (DTAB) at temperatures of 27 and 37?C, in 2.5 mM phosphate buffer, pH 6.4 by UV spectrophotometry, equilibriumdialysis and titration. The presence of 1.33 mM SDS caused histone H to fold and to further contact DNA. Binding data were use...

interaction between dna and histone h, was investigated in the presence and absence of sodium-n-dodecyl sulphate (sds) and dodecyl trimethylammonium bromide (dtab) at temperatures of 27 and 37?c, in 2.5 mm phosphate buffer, ph 6.4 by uv spectrophotometry, equilibriumdialysis and titration. the presence of 1.33 mm sds caused histone h to fold and to further contact dna. binding data were used in...

Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Interaction of Cisplatin with Cellular Macromolecules: A Fourier Transform Infrared Spectroscopy Study

Platinum is a metallic element, which may react with our cellular component through its involvement in cancer chemotherapy medications. Cisplatin is one of the most useful antineoplastic drugs against human ovarian carcinoma, which has the central element of platinum in its structure. The nature of chemical interaction between platinum and cellular macromolecules is yet to be understood. We exa...
