The solubility of chlorophenols as affected by surfactant was investigated. Three kinds of surfactant, sodium dodecyl sulfate, Triton X-100, and Brij 35, were utilized. The solubilization of chlorophenols by surfactant follows the order of 2,4,6-trichlorophenol > 2,4-dichlorophenol > 2,6-dichlorophenol > 2-chlorophenol; and the critical micelle concentration is an important index. The adsorption reactions of 2,4-dichlorophenol and 2,4,6- trichlorophenol onto hydrous montmorillonite in the presence of surfactant were examined. The presence of surfactant decreased the adsorption of chlorophenols significantly. The roles of hydrophobicity of chlorophenols in solubilization and adsorption behaviors are discussed.

To study the hemagglutinin of Fusobacterium nucleatum, methods were sought to solubilize and purify this component. When cells of F. nucleatum were ruptured by passage through a French press, the fragments lost virtually all ability to agglutinate human erythrocytes. Extraction of the fragments with 2% Triton X-100 for 30 min at 22 degrees C restored hemagglutinating activity (HA). Hemagglutination by these fragments could be inhibited by arginine, as can hemagglutination by intact bacteria. Treatment of active cell wall fragments with pronase and 2% Triton X-100-EDTA at 37 degrees C or with pronase and 0.1% Triton X-100-EDTA at pH 10.0 allowed recovery of solubilized HA. The former HA was inhibited by arginine (arg+) whereas the latter was not (arg-). Fractionation of the arg+ extract by preparative isoelectric focusing showed that HA was recovered from the gel sections having a pH between 4.5 and 5.5. Hemagglutination by this preparation was still arg+. Chromatography of this hemagglutinin on DEAE-Sephadex increased the specific activity to high levels with a loss of inhibition by arginine. A fraction from the DEAE-Sephadex column containing 10,700 HA units per mg of protein was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Solubilization at 22 degrees C before electrophoresis revealed three Coomassie blue-staining bands which migrated with apparent molecular weights of about 21,000, 38,000 and 60,000. When the same DEAE fraction was boiled in sodium dodecyl sulfate, electrophoresis revealed only one band with an apparent molecular weight of 21,000.

Background: The decellularized scaffold is a promising material for producing tissue-engineered vascular grafts (TEVGs) because of its complex, native-like three-dimensional structure and mechanical properties. Sodium dodecyl sulfate (SDS), one of the most commonly used decellularization reagents, appears to be more effective than other detergents for removing cells from dense tissues. The concentrations of SDS used in previous studies and their effects on decellularization are not consistent. Methods: In this study, porcine carotid arteries were decellularized using detergent-based protocols using Triton X-100 followed by SDS at different concentrations and exposing time. Cell removal efficiency and composition were evaluated by histological analysis, and DNA and collagen quantification. Ultrastructure, mechanical properties, pore size distribution, and in vivo biocompatibility of decellularized arteries were also evaluated. Results: The DNA content of decellularized scaffolds treated with 0.3% SDS for 72 h or 0.5% SDS for 48 h was significantly less than that treated with 1% SDS for 30 h. There was a significant loss of soluble collagen after treatment with 1% SDS relative to native arteries. The extensive loss of elastin and glycosaminoglycans was observed in decellularized arteries treated with 0.5% SDS or 1% SDS. The basement membrane and biomechanics were also damaged by these two protocols. Moreover, decellularized scaffolds became more porous with many large pores after treatment with 0.3% SDS. Conclusion: Low-concentration SDS could be a suitable choice for artery decellularization. Decellularized porcine carotid arteries, prepared using Triton X-100 followed by 0.3% SDS, may be a promising biological scaffold for TEVGs.
