Abstract
Latex particles were covalently linked to the 5'-proximal region of oligo(dT)30. The resultant oligo(dT)30-Latex was tested for its hybridizability to poly(A) containing mRNA. Several advantages were noted as compared to the conventional oligo(dT)30-cellulose column chromatography; (1) a highly efficient (approximately 95%) hybridization occurs in a short reaction period (10min), (2) more than 95% of poly(A) mRNA can be recovered from oligo(dT)30-Latex by a simple heating followed by brief centrifugation, (3) multiple samples can be handled simultaneously and moreover, (4) the poly(A)-mRNA on the oligo(dT)30-Latex can be directly transcribed by AMV reverse transcriptase to form the cDNA. These properties of oligo(dT)30-Latex promise an excellent reagent for nucleic acid technology.
