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 is investigated.[1]

Application

Cyanogen bromide (CNBr) solution may be used in the cyanogen bromide method for covalent immobilization of trypsin onto poly(2-hydroxyethyl methacrylate)/ polystyrene composite microspheres.[2] It may be used in the preparation of CNBr-activated diol-silica, useful as silica support in HPLC.[3]

To obtain silica supports for high-performance affinity chromatography, a method of preparing CNBr-activated diol-silica under anhydrous conditions was developed. Activation of the silane-derived hydroxyls with cyanogen bromide and triethylamine was optimized and demonstrated to efficiently couple several amino ligands (tryptophan

Cyanogen bromide has been found to induce the template-guided condensation of oligonucleotides only in the presence of N-substituted morpholines. Based on 31P, 1H and 13C NMR spectroscopy data, the mechanism of the phosphomonoester group activation by cyanogen bromide in N-substituted
