title: A method for generating sticky-end PCR products which facilitates unidirectional cloning and the one-step assembly of complex DNA constructs.
abstract: We have developed and tested a method for the restriction enzyme-independent generation of sticky-end PCR products. The method is suitable for use with a proof-reading polymerase such as pfu, or any other heat-stable polymerase which produces a blunt-end product. The technique can be used to achieve unidirectional cloning of PCR products with an efficiency greater than 90%. Because the sequences of the sticky ends are defined by the user and potentially can be of any length, the method can also be exploited for the one-step construction of recombinant plasmids from multiple functional cassettes, without the use of restriction enzymes.
