An ITR Faceoff

AAV ITRs versus Transposon ITRs

Inverted Terminal Repeats (ITRs) are DNA sequences flanking the transgene of interest to signal incorporation into adeno-associated virus (AAV) or genome insertion by transposases. Despite sharing the ITR element name, viral vector and transposon ITRs differ in sequence and important properties that need to be considered in handling these vectors.

Why E. coli rocks

Commonly, when a person hears about Escherichia coli (E. coli), the news is negative. But it’s only a specific strain of E. coli detected on food that wasn’t cleaned or stored properly that’s a health hazard. When it comes to biotech, however, E. coli rocks! It’s been the workhorse for the creation of a multitude of products due to:

Eliminate Protein and Antibiotic Markers

Advantages of the Nanoplasmid RNA-OUT Marker System

For decades, the same plasmid technology has been used in vaccination, cell and gene therapy, and as a raw material in viral vector and RNA production, but that technology often isn’t a good fit for the processes where it’s being used. Now, with the growing availability of Nanoplasmid™ vectors, that is changing.

A Focus on Analytics, for RNA and Beyond

Driving innovation of industry tools

Analytical innovation is often overlooked in discussions of biotechnology product development and manufacturing processes. For example, in the DNA area, most “state of the art” analytical methods in use were developed in the 1980s, or even earlier. Industrywide, there is a need to continuously innovate in the analytical space due to the tremendous advances in enabling technologies.

Webinar on Demand: Advanced Plasmid Technology – Improving Safety and Performance

Nanoplasmid™ Vectors: The Power of Small

In cell and gene therapies, delivery is a critical factor. Regardless of your modality, optimizing payload, impact, and duration are common challenges. Countless programs, globally, are working on the delivery mechanism. However, many have overlooked a key component in improving therapeutic or manufacturing performance: the plasmid.

A Complete Suite of rAAV Constructs

New ITR Cloning and Reporter Constructs Now Available
By Jeff Briganti, Senior Director, Global Strategic Marketing

Manufacturing standardization for cell and gene therapies (C&GT) has received increased focus in the last several years, spurred by the rapid exponential growth witnessed in this field. The resulting need for improved access to high-quality raw materials, including plasmid DNA, has made standardization integral to streamlining the development process for this biologic product category.

For recombinant adeno-associated virus (rAAV) viral vector production, we now offer several off-the-shelf ITR cloning backbones and GFP reporter constructs to complement our standardized set of OTS helper and packaging plasmids. This product set is available license and royalty free for research through commercial rAAV applications.

Utilizing this standardized portfolio can provide significant time and cost reduction, expediting time to market and de-risking specialized, transformative therapeutic development. By partnering with a contract development and manufacturing organization (CDMO) offering a complete suite of plasmids for viral vector production, researchers can streamline their upfront development while minimizing supply chain disruption throughout their program’s lifecycle.
