Enzymatic synthesis of solid phase-bound DNA sequences corresponding to specific mammalian genes

With oligo(dT)-cellulose as primer, RNA-dependent DNA polymerase catalyzes the synthesis of cellulose-bound DNA that is complementary to mouse globin mRNA. The resulting cellulose-bound or solid phase complementary DNA hybridizes specifically with globin mRNA and permits the recovery of intact globin mRNA. This simple technique for the synthesis of solid phase-bound complementary DNA provides an additional and convenient method for the purification of specific genetic sequences.
