WebImaged capillary isoelectric focusing (icIEF) is a gold standard method for characterizing the charge heterogeneity of protein therapeutics. A broad range of protein therapeutics such as monoclonal antibodies, antibody-drug conjugates (ADCs), and fusion proteins are routinely analyzed by icIEF due to its high resolution and high reproducibility. WebThis high-resolution cIEF method also may also give insights into the charge heterogeneity characteristics of AAVs. Indeed, multiple peaks were observed for the empty as well as full capsids of this set of AAV 8 samples, which could indicate the charge heterogeneity. Further experiments are needed to validate this claim. chiropractic referral boards https://cannabimedi.com
