Webinar: Exploring the Charge Heterogeneity in Recombinant Adeno-Associated Virus with Imaged Isoelectric Focusing

Webinar Summary

Recombinant Adeno-associated Virus (rAAV) is one of the leading platforms for monogenic disease therapy. One of the attractive features of rAAV is its wide tropism, owing in part to its surface property where charged amino acids are not conserved. In addition, charged regions are involved during its transduction of host cells. As a result, the characterization of its charged surface is necessary for understanding rAAV function. Here we present the exploration of the rAAV’s charge profile and give a fingerprint of the charge profile, thus demonstrating the potential application of charge fingerprinting for formulation development under elevated temperature and pH stress.
