GMP Viral Vector, Gene Therapy and Vaccine Manufacturing

Put our GMP expertise to work for you.

ABL has a long history of development and manufacturing of preclinical and clinical virus-based biologics. From 30 years of groundbreaking work with HIV to supporting the latest gene therapy technologies, ABL offers a comprehensive portfolio of services for the effective design, development, manufacturing and analytical testing of vaccine and virus vector products.

Viral vectors, gene therapy, viral vaccines, oncolytics, and other immunotherapies

single-use bioreactors

ABL has produced breakthroughs in viral technologies since its inception including the isolation and characterization of the first human retroviruses (HTLV-I and HTLV-II), early research on human immunodeficiency virus (HIV-I) and its characterization as the etiology of AIDS, and the development of one of the first diagnostic HIV-1 blood tests.  This expertise in virology has made ABL an industry leader in supporting the development and GMP manufacture of gene therapies, viral vaccines and other virus-based technologies for clients around the world.

ABL provides manufacturing and development services to support viral based products including; Master and Working Cell Banks (MCB/WCB), Master and Working Virus Seed Stocks (MVSS/WVSS), GMP drug substance manufacturing for viral vectors and vaccines, GMP aseptic filling of live virus in vials, and GMP QC testing.

We routinely work with our clients to advance their production process from the bench to a scalable, GMP-compliant process that will support IND studies.  Early activities can include adaptation of cell lines from adherent to suspension growth, plaque purification of virus seed, development and optimization of large-scale transient transfection manufacturing, optimization of upstream and downstream processes, and development of quality control methods for release and stability testing.
