With over a decade of experience synthesizing DNA, GENEWIZ has developed a unique adeno-associated virus (AAV) plasmid synthesis service, the first of its kind on the market. This service provides researchers working with adeno-associated virus vectors with synthesis and cloning of transgene expression cassettes into custom AAV vectors with high efficiencies. GENEWIZ’s AAV plasmid synthesis service comes bundled with our new AAV plasmid preparation protocol to deliver mini- to giga-scale AAV plasmids that have been sequence-verified by our AAV-ITR Sanger sequencing service.
We understand the importance of intact inverted terminal repeat (ITR) regions in downstream AAV gene therapy applications, as seen in recent publications, therefore GENEWIZ maintains a 2-step QC process and ITR correction by gene synthesis to ensure the integrity of your ITR regions.
Extensive experience working with a wide variety of custom AAV vectors with ITR synthesis capability
FREE codon optimization tools based on an advanced algorithm for high protein expression
Ensure intact ITR regions before and after cloning with our robust 2-step QC system including sequence verification using GENEWIZ’s proprietary AAV-ITR sequencing and ITR correction via gene synthesis
Mini- to giga-scale preps using proprietary AAV plasmid preparation protocol
