AAV-ITR Sequencing

GENEWIZ AAV-ITR Sequencing sequences difficult inverted terminal repeat (ITR) regions of adeno-associated virus (AAV), to expedite screening and validation of leads.

This newly-developed protocol prevents abrupt reduction in the sequencing signal at the start of the ITR hairpin and reads through the full length of the ITR region. AAV-ITR sequencing can be combined with our Primer Walking service to sequence whole AAV vectors.

    Tech Note | An Efficient and Reliable Approach to AAV Packaging

    While AAV is a powerful vehicle for gene delivery, unstable ITRs threaten the fidelity of rAAV genomes. Loss of ITR integrity diminishes the packaging efficiency of rAAV particles and thus viral titer. In this tech note, discover the effect of partial and full ITR deletions on AAV packaging and how to reliably identify and effectively correct them.

    The adeno-associated virus (AAV) is a powerful vehicle for gene therapy; however, working with AAV vectors can be challenging. Spontaneous mutations in the inverted terminal repeat (ITR) regions can accumulate during plasmid propagation in bacteria. Find out how our scientists have optimized the AAV plasmid preparation process to deliver 100% accurate constructs.
