PURPOSE: Micellar solubilization is a powerful alternative for. Done regarding solubilization of drugs by micelles is presented. Abstract: In this paper, the use of surfactants for solubilization of. solubilization techniques pdf Polyelectrolytes, pH, and temperature on dye solubilization has been.Solution chemistry, solubility and solubilization. Dissolution limited bioavailability is a very c...
A method was found for the in situ activation of the latent Ca(2+)-ATPase of the coupling factor from chloroplasts of Euglena gracilis and its resultant solubilization. The activation causes the concomitant solubilization of the enzyme and facilitates easy and nearly complete extraction. The activation consists of lowering the pH of isolated chloroplasts for 2 minutes to pH 4.5 to 4.7 with acet...
The occurrence of both acid and alkaline ribonuclease activities in liver and kidney was reported in 1954 by Roth (1) and by de Lamirande et al. (2). Since then, investigators have used various methods to purify the intracellular ribonuclease activities (3-8). In our studies, comparatively mild procedures were used for the nuclease preparations (5)) with the hope that the nuclease activities as...
When Nil2C2, a metastatic clone derived from hamster embryo fibroblasts (Nil), was inoculated over [3H]leucine-labeled fixed cells, Nil2C2 cells solubilized and phagocytosed fixed cells, and the radioactivity was released into the culture medium as trichloroacetic acid-soluble fragments. The solubilization of fixed cells was dependent on both the time of incubation of living cells with fixed ce...
The enzyme quinoprotein glucose dehydrogenase (GDH) catalyses the oxidation of glucose to gluconic acid by direct oxidation in the periplasmic space of several Gram-negative bacteria. Acidification of the external environment with the release of gluconic acid contributes to the solubilization of the inorganic phosphate by biofertilizer strains of the phosphate-solubilizing bacteria. Glucose deh...
this study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by astm d- 6751. accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . alkaline catalysed transesterfication was carried out by using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...
Pluronic/bile salt/phospholipid mixed micelles (Pluronic/BS/PS-MM) drug carrier system for solubilization hydrophobic drugs was developed. A typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. Five Pluronics, F68, F88, F98, F108, and F127 with different PPO chain length were studied. CMC data and solubilization capacities w...
