White to yellow powder | [Uses]
1-Cyano-4-(dimethylamino)pyridinium tetrafluoroborate is a cyanylation reagent for protein sulfhydryl groups and used to prepare protein-polysaccharide conjugates. It is employed as an activating agent for polysaccharide resins and conjugation of lipopolysaccharides while retaining endotoxic activity. | [Biological Activity]
CDAP is a cyanylation reagent for protein sulfhydryl groups which is used to prepare protein-polysaccharide conjugates. CDAP is also an activating agent for polysaccharide resins and is used for the conjugation of lipopolysaccharides while retaining their endotoxic activity.
CDAP is considered to be a less toxic reagent as compared to cyanogen bromide (CNBr) (a known polysaccharides activator). In additionCDAP is easier to use as it can be employed at a lower pH and has fewer side reactions. It is known th at CDAP polysaccharide activation efficiency is optimal at pH 9-10. It was also reported th at direct conjugation of protein to CDAP-activated polysaccharides can be performed under mildly alkaline conditions (pH 7-9). It has also been reported th at proteins could also be conjugated to CDAP-activated polysaccharides at pH 5. |
