64x bio says a new cell screening technology has the potential to make viral vector production more efficient. The San Francisco-headquartered biotechnology’s “VectorSelect” platform is a high throughput screening technology designed to help viral manufacturers identify high yield production cell lines. 64x bio says the system’s key feature is “genetic barcoding,” which links information on viral vector productivity to the parent cell allowing users to screen millions of candidate production cell lines at once. The aim is to help firms…
