Charles River Launches Viral Vector Reference Materials to Streamline the Transition to GMP

Supporting scale-up for early-phase AAV- and LVV-based gene and gene-modified cell therapy researchers and developers

Charles River Laboratories International, Inc. (NYSE: CRL) today announced the launch of its reference materials for adeno associated virus (AAV) and lentiviral vector (LVV) portfolio, designed to streamline Cell and Gene Therapy (CGT) research and development as it scales to Good Manufacturing Practice- (GMP) quality.

Moving towards a gold standard for reference materials, Charles River is introducing six AAV reference material serotypes, offering superior empty and full capsid ratios and high vector genome concentration (GC/mL), plus five LVV reference material products, available with different combinations of promoters and reporter genes. The additional reference materials add to the Company’s extensive portfolio of plasmid and viral vector contract development and manufacturing organization (CDMO) offerings, reinforcing its concept-to-cure commitment to CGT researchers and developers by enabling partners to navigate the path from early discovery to commercial.

ASGCT Launch

Charles River will officially launch its AAV and LVV reference materials with supporting case study data during the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting, May 7 – 11, 2024, in Baltimore, MD.
