Before revision: The principle of solid phase DNA sequencing was described in 1989 based on binding of biotinylated DNA to streptavidin coated magnetic beads and elution of one DNA strands selectively using alkali.
After revision: The principle of solid phase DNA sequencing was described in 1989 based on binding of biotinylated DNA to streptavidin-coated magnetic beads and elution of single DNA strands selectively using alkali.
