Macro mass photometry enables comprehensive analysis of lentiviral populations and associated impurities

Characterizing the purity of viral vectors such as adenoviruses (AdVs) or lentiviruses (LVVs) for use in cell and gene therapies presents sizeable challenges. Some currently used techniques, like NTA, struggle to resolve all populations in a sample a

In this application note we show how, using LVV samples from Minaris’s XOFLX® Producer Cell Line, macro mass photometry (macro MP) resolves distinct particle populations, tracking LVV enrichment, purity, and physical titer in near-real-time across do

Explore exclusive Refeyn offers to enhance your mass photometry investment with special savings on TwoMP, SamuxMP & KaritroMP instruments and accessories.

Macro mass photometry (MMP) can resolve and quantify multiple particle populations, providing critical information about complex samples of adenoviral (AdV) and lentiviral vectors (LVV). Here, we demonstrate the principles behind the multiparametric
