Interpretive Summary: Molecular biology allows one to combine different pieces of DNA for study and analysis. Invitrogen Gateway technology exploits the integrase/att site-specific recombination system for directional cloning of PCR products and the subsequent subcloning into destination vectors. We created a construct to easily convert any available Gateway destination vector to a MultiSite Gateway vector in a single recombination reaction. Our tool makes MultiSite Gateway a more widely accessible technology and expands its applications by exploiting all the features of the Gateway vectors already available.

Technical Abstract: We created a construct, pDONR-R4-R3, to easily convert any available Gateway destination vector to a MultiSite Gateway vector in a single recombination reaction. In addition, we designed pDONR-R4-R3 so that DNA fragments already cloned upstream or downstream of the Gateway cassette in the original destination vectors can still be utilized for promoter-gene or translational fusions after the conversion.
