title: Inhibition of deacylation and improvement in N-hydroxysuccinimide ester modification of phenylalanyl-tRNA by dimethyl sulfoxide.
abstract: We have found that dimethyl sulfoxide significantly inhibits deacylation of Phe-tRNA. This allows a high pH in N-hydroxysuccinimide ester reactions while maintaining a high level of aminoacylated tRNA, improving the overall yield of the Phe-tRNA modification reaction.
