The molecular-weight distribution of glycosaminoglycans.
1. A rapid and sensitive method for the accurate estimation of the molecular-weight distribution of keratan sulphate and chondroitin sulphate isolated from adult bovine nasal septum and intervertebral disc is described. The method utilizes gel chromatography of reductively labelled glycosaminoglycan and end-group estimation of number-average molecular weight for each fraction across the peak of...
متن کاملImmunization of dog with proteins under 30 kDa molecular weight of hydatid cyst fluid and protoscoleces of Echinococcus granulosus
The aim of the present study was to assess the immunogenicity of under 30kDa molecular weight proteins of hydatid cyst fluid and protoscoleces in dogs experimentaly Infected with Echinococcus granulosus. Isolation of under 30 kDa proteins performed using Millipore filter. Six dogs were used in three groups: 2 dogs with under 30 kDa proteins of hydatid cyst fluid (Group I); 2 dogs with proteins ...
متن کاملMolecular Weight Distribution of Proteins Synthesized in Single, Identified Neurons of Aplysia
Parietovisceral ganglia from Aplysia californica were incubated in medium containing leucine-(3)H. Single, identified nerve cell somas were isolated from the ganglia, and their proteins extracted and separated by electrophoresis on 5% SDS-polyacrylamide gels. The distribution of total or newly synthesized proteins from the single neurons was determined by staining or slicing and liquid scintill...
متن کاملMolecular Weight, Molecular Volume, and Hydration of Proteins in Solution
1. The gram molecular weight of a substance may be calculated from the osmotic pressure of its solution. 2. The radius of the hydrated molecule and, hence, the gram molecular volume of the hydrated solute may be determined from diffusion measurements. The hydration of the molecules may, therefore, be calculated from osmotic pressure and diffusion measurements. 3. Hydration may also be determine...
