in this work attempts were made to evaluate k+-sds and hydrocolloid polymer-sds interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. different dispersions of micronized megestrol acetate and sds were prepared. kcl and kh2po4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

The interaction of sodium n-dodecyl sulphate (SDS) with histones in phosphate buffer pH 6.4 has been studied spectroscopically and by equilibrium dialysis. The enthalpies of interaction and the spectroscopic data suggest different structural stability for histones-SDS interaction. The linear relation between enthaly and absorbtion was determined by the equation of m= , where m is the sta...

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...
