An expeditious and accurate simplification of Stone and Scallan's solute exclusion technique was developed, thereby avoiding several sources of experimental error coupled with the determination of cellulose pore volume. Using this method, it is shown that cellulolytic enzymes do not enter into the micropores of five studied celluloses. These results suggestes that hydrolysis occurs initially at...

A method for solubilization of pristine fullerene (C(60)) in water was proposed by directly using bovine serum albumin (BSA) as a "solubilizer" by means of the unfolding mechanism. C(60) aqueous solution with a small distribution size, excellent dispersion stability and high dispersion concentration was obtained without the use of derivatization and organic solvent.

Conjugates of bovine serum albumin with progesterone, deoxycorticosterone, and estrone have now been synthesized as an extension of a program to prepare and characterize steroid-protein conjugates with the ultimate purpose of testing their ability to stimulate the formation of antihormonal antibodies (1). The steroid derivatives which were coupled to albumin are shown in Fig. 1. The synthetic a...

Light scattering measurements have been made on solutions of hyaluronic acid in the presence and absence of bovine serum albumin. The results are interpreted as showing an exclusion of bovine serum albumin from molecules of hyaluranic acid, the magnitude of which agrees with most other measurements of exclusion. The theory of the effect of heterogeneity of exclusion is given. The apparent heter...

A simple, relatively precise, and clinically applicable indirect method of determining relative cardiac output is presented. The principle involved is a modification of the dye-dilution principle and is performed by external monitoring of intravenously injected radioiodinated serum albumin combined with a standard detecting and recording device. This procedure was performed serially before and ...

Dielectric and conductivity measurements are reported for bovine serum albumin as a function of hydration. Strong evidence is found for the existence of mobile charges whose short- and long-range hopping motion strongly depends on the physical state of the protein-bound water. These charges are considered to be protons. Insights into the nature of the electrical properties of protein-methylglyo...

BACKGROUND It is well-known that albumin is synthesized in the liver; serum albumin is a major component of serum proteins. However, it has not been well elucidated how dietary protein intakes are associated with serum albumin levels in general populations without extreme malnutrition. We cross-sectionally investigated in the representative Japanese the association between dietary protein intak...

human serum albumin has been used as a model protein for protein folding and ligand binding studies over many decades. due to its long life period and high concentration in plasma, hsa is highly sensitive to glycation. it is reported that 175 mg/dl glucose concentration is a threshold of kidney activity for the beginning of excretion of glucose. ph denaturation of hsa in absence and presence of...

A quantitative method was developed for the determination of proteins in aqueous solution. Under optimal conditions, the linear ranges of calibration curves for the determination of bovine serum albumin (BSA), human serum albumin (HSA) and egg albumin (Alb) were 01.13 μg ml-1, 0-1.17μg ml-1 and 0-1.13μg ml-1, respectively. The detection limits were 15.74 ng ml-1 for BSA, 23.34 ng ml-1 for HSA a...

Immunological tolerance produced in rabbits by neonatal injections of BSA can be terminated by a series of injections of certain heterologous serum albumins which cross-react with BSA. Injections of albumins distantly related to BSA were more effective in terminating the tolerant state than injections of albumins closely related to BSA. It was concluded from results obtained with several hetero...
