General description

Cyanogen bromide solution induces template-guided condensation of oligonucleotides only in the presence of N-substituted morpholines. Mechanism of the phosphomonoester group activation by cyanogen bromide in N-substituted morpholine buffers has been investigated.

Application

Cyanogen bromide is a general reagent used to cleave carbon-heteroatom bonds. It is used in the synthesis of organocyanamides from corresponding tertiary amines, which is popularly known as von Braun reaction. CNBr solution is widely used in protein immobilization and cleavage.

The conjugation of polysaccharides with an effective carrier protein is critical for the development of effective bacterial polysaccharide vaccines. Therefore, the identification and optimization of carrier proteins to induce an effective immune response is necessary for developing a combined vaccine.
