“…In other papers (48,49) (points k and l), commercial samples were used without further purification; no evidence was provided for the quality of the samples used. Auxiliary quantities, such as the refractive index increment of micelles in light scattering experiments show wide variations (33,(40)(41)(42)(43)45) (points c to f, h). Some authors used the molar mass of sodium deoxycholate monomer (Mo = 414.55 g mole-') in calculating the aggregation number from the measured molar mass of the micelles; others used the molar mass of the deoxy-cholate anion (Mo = 391.55 g mole-') (the first value should be used!).…”

The current state of the knowledge of the size and the aggregation numbers of micelles formed in solutions of bile salts was evaluated. The experimental techniques considered include static light scattering, sedimentation equilibrium, membrane osmometry, sedimentation velocity and transla‐tional diffusion. The theoretical background of each method is briefly discussed, the working equations are summarized, and the limitations of each technique are enumerated. Various interaction parameters and their effects on the measured micellar size are discussed. A brief survey of the recent experimental results from the author's laboratory is presented.

“…The CMC may be determined by a number of methods, each giving somewhat different values because they measure different physical properties or perturb the system differently. The methods currently used for studying aggregation properties of bile salt solutions include surface tension (81,96,98,129), dye solubilization (96), light scattering (26,60,72,107), kinetic dialysis (62), NMR spectroscopy (31,57,79), X-ray scattering (31), spectral shifting (37,96), and photon correlation spectroscopy (97). Even the results of a stated method may differ because the techniques are used differently by different investigators.…”
