Abstract

Hybridization buffers, for hybridizing complementary polynucleotides, contain polyvinyl alcohol (MW 1000-20000) and/or polystyrene sulphonic acid (e.g. MW 60000-80000) as a rate enhancer, generally at a concentration of 1-10%. Dextran sulphate, polyethylene glycol and cationic detergents may be additionally present. The method is useful when one of the two complementary polynucleotides is immobilised, or is in in situ hybridizations.
