ЗАСТОСУВАННЯ МЕТОДУ ЕЛЕКТРОФОРЕЗУ ДЛЯ АНАЛІЗУ ГЕТЕРОГЕННОСТІ ХІТОЗАНУ ЗА МОЛЕКУЛЯРНОЮ МАСОЮ

Анотація

Method of chitosan electrophoresis in PAG at pH 4,5 with a stepwise gradient of acrylamide concentration of 5, 10, 15, 20 % was developed which permits to analyse the distribution of chitosan molecules in a specimen after their mol. mass and to determine the content of each fraction. Characteristic densitometric profile of phoretogram can be used for identification of chitosan types.
