In 1885-6 Kauder observed that globulin was precipitated from serum when the concentration of ammonium sulphate reached 24 to 29 per cent of full saturation and that its precipitation was complete when the concentration reached 36 to 46 per cent of complete saturation. Thereafter no further precipitation took place until the concentration reached 64 per cent of full saturation, when albu-min st...

IN this paper, 'which is the concluding one of the series, we are concerned with the fractionation, by means of a neutral electrolyte and electrodialysis, of a few sera which have already been investigated in the ultracentrifuge [McFarlane, 1935, 1, 2, 3]. The particular objects in view have been (1) to investigate the composition of the globulin fractions obtained by a single precipitation wit...

This Research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated Fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. Applied nutrients were zinc sulphate (Zn) of 0.0 and 1.5gl-1 and urea (N) at 0.0 and 5 gl-1 and Fe (1) control (low Fe)...

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...

The thermodynamic parameters of interaction between calf thymus histone H A and dodecyl trimethyl ammonium bromide (DTAB), a cationic surfactant, in aqueous solutions of pH 3.2, 6.4 and 10.0 were measured over a wide range of DTAB concentrations by equilibrium dialysis at 27°C and 37°C and are discussed. The data are used to determine the free energy from the Wyman binding potential theore...
