Main Factors Affecting the Stability of Colloids
A general survey is given on the role that interparticular attraction forces play in the aggregative stability of colloidally dispersed systems. Special attention is paid to the disjoining pressure acting between interlayers. The importance of recent results obtained by the author using the so-called flow ultramicroscope method is emphasized as these data allow the interpretation of the kinetic...

متن کاملFactors affecting urinary myoglobin stability in vitro.
Urine myoglobin concentrations are measured clinically to assess rhabdomyolysis and the related risk of renal damage. We studied urine myoglobin concentrations in vitro to explore the factors affecting stability. Myoglobin was very unstable in urine specimens, especially below pH 6.5, and its immunoreactivity deteriorated rapidly with increasing temperatures. The deterioration rate was influenc...
متن کاملFactors affecting storage stability of various commercial phytase sources.
A 360-d study was performed to evaluate the effects of different environmental conditions on storage stability of exogenous phytases. Coated and uncoated products from 3 phytase sources [Ronozyme P (DSM Nutritional Products, Basel, Switzerland), OptiPhos (Phytex LLC, Sheridan, IN), and Phyzyme (Danisco Animal Nutrition, Marlborough, UK)] were stored as pure forms, in a vitamin premix, or in a v...
متن کاملYeast alpha-isopropylmalate isomerase. Factors affecting stability and enzyme activity.
Yeast alpha-isopropylmalate isomerase was found to be markedly stabilized by high concentrations of glycerol and (NH4)2SO4. Such conditions of high ionic strength inhibited the enzyme, stabilized the enzyme to heat, and affected kinetic parameters. The isomerase was found to exhibit ionic strength-dependent hysteresis when enzyme, totally but reversibly inhibited by storage under conditions of ...
