Abstract
A cartridge containing a dry polymer composition carrying trapped biopolymer subunits for use in synthesis of biopolymer chains provides a discrete unit for stepwise supply of subunits, such as protected amino acids, in an automated apparatus for biopolymer synthesis. The composition is swellable in organic solvent to release and supply the subunits to a growing biopolymer chain immobilized on a polymer support. An automated synthesizer uses the cartridges for sequential subunit supply and monitors conductivity of deprotection reagents to control cycling and timing of steps.
