Abstract
Summary The following procedure is used in a rapid isolation of a specific (isoacceptor) tRNA from a mixture of deacylated tRNAs: (1) Acylation with the amino acid corresponding to the desired specific tRNA (2) Reaction of the specifically acylated tRNA with a new bi-functional reagent (PAMBSYL) (3) Binding of the pambsylated tRNA to a sulfhydryl-containing resin (4) Release of the specific tRNA from the resin after removal of the non-reacted tRNA. Steps 3 and 4 can be carried out in 20 min. One ml of the resin can bind approximately 200 mg of reacted tRNA.
