Previously Vilker et al. (J. Colloid Interface Sci. 79(2), (1981)) reported the osmotic pressure of concentrated bovine serum albumin (BSA) up to 475 g/L in 0.15 M sodium chloride at pH 4.5, 5.4, and 7.4. The authors used a semiempirical model based on Donnan theory to predict the osmotic pressure w

## Isotachophoretic analysis of the pH dependent carrier properties ofbovine serum albumin for rifamycin AF/O 13 The binding sites of bovine serum albumin for rifamycin AF/O13 were examined by means of analytical capillary isotachophoresis. At pH 7.5-7.9, there was only one binding site on non-def
## Abstract We propose simple expressions $\Pi /\Pi \_0 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{3\alpha - 1}$ and $(\delta \_0 /\delta )^2 = 1 + (\varphi /\varphi \_{{\rm ex}} )^{2\alpha }$ for the osmotic pressure Ξ and the depletion thickness __Ξ΄__ as a function of the polymer concentration __Ο__
## Abstract Two endothermic peaks could be observed for five commercial samples of bovine serum albumin (BSA). The smaller peak observed by differential scanning calorimetry (DSC) corresponded to enthalpy relaxation. This peak was followed on storage of BSA, in its glassy state, after it had been h
