CA 2596653

A purification process for the capsular polysaccharide of S.agalactiae in which the saccharide is initially treated with an aqueous mixture of an alcohol and a calcium salt, followed by precipitation with a cationic detergent. The process can be completed in less than three days and has a yield of around 60%. It avoids the need for DNase, RNase and/or protease treatment. The saccharides of the process have a very low protein contamination and a very low absorbance at 280nm.

L'invention concerne un procédé de purification pour polysaccharides capsulaires de type S. agalactiae, selon lequel les saccharides sont tout d'abord traités avec un mélange aqueux à base d'alcool et de sel de calcium, ledit traitement étant suivi par la précipitation d'un détergent cationique. Le procédé peut être effectué en moins de trois jours et présente un rendement d'environ 60 %. Ledit procédé évite d'avoir recours à un traitement par DNase, RNase et ou protéase. Les saccharides selon le procédé présentent un taux très réduit de contamination protéinique et un taux d'absorbance très réduit à 280 nm.
