Detect Viral Contamination in your mAb process

Production processes should be free from detectable adventitious agents. Traditional tests for adventitious viruses offer opportunities for broad detection of diverse viruses however, these are time consuming tests and have limitations in terms of sensitivity and identification of specific contaminants. Molecular testing technologies such as Polymerase Chain Reaction (PCR) and Next Generation Sequencing (NGS) complement traditional cell-based methods, opening doors for more rapid, sensitive detection of viral contaminants.

1. Accelerate biosafety testing of biological therapies

Traditional approaches to virus detection– cell-based and in vivo assays - have served the biopharma industry very well over the years, but they have a long turn-around and do not identify specific contaminants. New molecular methods such as broad specificity degenerate PCR, and next generation sequencing (NGS) have been developed not only to replace or supplement traditional test methods but also expand the detection capabilities, thus expediting viral safety testing.

The Blazar™ platform provides researchers with accurate and highly sensitive viral detection in just days. Combining the breadth of detection of NGS with the speed and sensitivity of PCR, Blazar™ platform relies on degenerate PCR primers for coverage of more than 5000 viral variants. By amplifying multiple targets within a conserved region of the viral family genome, Blazar™ platform detects a much broader range of adventitious viruses as compared to traditional PCR methods.

Cell line characterization

Cell Line Characterization is required by the regulatory bodies to confirm the species origin and history of the cell line; and characterize and test the identity, stability and purity.



3. Confirm that adventitious agents are not present in raw materials and bulks

Variability is inherently introduced by bioprocessing raw materials. A detailed initiative to fully characterize raw materials using orthogonal techniques can provide assurance that the raw materials are fit for purpose.

4. Detect emerging viruses in raw materials

Viral contamination is a constant challenge to all biopharmaceutical production processes. Emerging viruses are of particular concern and need to be characterized to understand the potential threat to your process. Understanding the susceptibility of your raw materials to these viral contaminants, and the capability of classical assays to detect them, will affect your viral safety strategy.
