Lysozyme-dextran core-shell nanogels prepared via a green process.
A novel method has been developed for preparing nanogels with a lysozyme core and dextran shell. The method involves the Maillard dry-heat process and heat-gelation process. First, lysozyme-dextran conjugates were produced through the Maillard reaction. Then, the conjugate solution was heated above the denaturation temperature of lysozyme to produce nanogels. The nanogels are of spherical shape...
متن کاملFunctional Changes of Lysozyme by Conjugating with Carboxymethyl Dextran.
Hen egg lysozyme-carboxymethyl dextran (HEL-CMD) conjugate was prepared by using water-soluble carbodiimide as a model protein-acidic polysaccharide conjugate for improving the protein function. An acid-amide bond between HEL and CMD was confirmed by SDS-PAGE, isoelectric focusing and IR spectra. The molar ratio of CMD to HEL in the conjugate was 1:1. The isoelectric point of the conjugate was ...
متن کاملStability and Biological Activity Evaluation of Chlorantraniliprole Solid Nanodispersions Prepared by High Pressure Homogenization
Poorly water-soluble compounds are difficult to develop as pesticide products and face great challenges in water-based and environmentally friendly formulation development. In this study, high pressure homogenization combined with lyophilization was adopted to prepare the solid nanodispersions of chlorantraniliprole with poor solubility and high melting point. The mean particle sizes of the sol...
متن کاملInactivation of gram-negative bacteria by lysozyme, denatured lysozyme, and lysozyme-derived peptides under high hydrostatic pressure.
We have studied the inactivation of six gram-negative bacteria (Escherichia coli, Pseudomonas fluorescens, Salmonella enterica serovar Typhimurium, Salmonella enteritidis, Shigella sonnei, and Shigella flexneri) by high hydrostatic pressure treatment in the presence of hen egg-white lysozyme, partially or completely denatured lysozyme, or a synthetic cationic peptide derived from either hen egg...
متن کاملHigh-pressure protein crystallography of hen egg-white lysozyme
Crystal structures of hen egg-white lysozyme (HEWL) determined under pressures ranging from ambient pressure to 950 MPa are presented. From 0.1 to 710 MPa, the molecular and internal cavity volumes are monotonically compressed. However, from 710 to 890 MPa the internal cavity volume remains almost constant. Moreover, as the pressure increases to 950 MPa, the tetragonal crystal of HEWL undergoes...
