Chromatography on Sephadex LH20 as an efficient purification step after removal of internucleotide 2,2,2-trichloroethyl protective groups from oligoribonucleotide phosphotriesters.

Nucleic acids research, 1981
Chromatography on Sephadex LH20, in a linear gradient of methanol in 0.02M TEAB buffer pH 7.5, is proposed as a fast and efficient method for the isolation and purification of protected oligoribonucleotide phosphodiesters obtained by deprotection of internucleotide phosphotriesters, and for the monitoring of the deprotection step itself. Its utility is
