설명

Application

1-Cyano-4-dimethylamino pyridinium tetrafluoroborate can be used in vaccine research for the conjugation of polysaccharides with proteins

Biochem/physiol Actions

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 addition, CDAP is easier to use as it can be employed at a lower pH and has fewer side reactions. It is known that CDAP polysaccharide activation efficiency is optimal at pH 9-10. It was also reported that direct conjugation of protein to CDAP-activated polysaccharides can be performed under mildly alkaline conditions (pH 7-9). It has also been reported that proteins could also be conjugated to CDAP-activated polysaccharides at pH 5.

Features and Benefits

• Readily available solution, that reduces the need for preparation time
• Versatile and adaptable for vaccine and biochemical research

General description

1-Cyano-4-dimethylaminopyridinium tetrafluoroborate (CDAP) is crucial in vaccine and biochemical research. It rapidly activates polysaccharides, like TI-2 antigens, in a short time. Further, CDAP enables protein conjugation, vital for creating conjugate vaccines that enhance immune responses. CDAP works effectively at both pH 9-10 and mild alkaline conditions (pH 7-9), making it versatile for various antigens. CDAP′s efficacy in inducing high antibody levels makes it invaluable for developing effective vaccines and immunological reagents.

Preparation Note

Polysaccharide conjugation: CDAP Ready Made Solution (100mg/mL in acetonitrile) should be added in a ratio of 1mg CDAP to 1mg polysaccharide while vortexing (Example: per 1mg polysaccharide add 10μL of CDAP Ready Made Solution). Add 0.2M triethylamine, 10μL per 1mg polysaccharide to raise the pH of the reaction.
