Peptide mapping of adeno-associated virus capsid proteins
23 Feb 2023In this application note, Phenomenex profiles capsid protein peptides from AAV5 and AAV9, digested with trypsin using a BioZen™ Peptide XB-C18 reversed phase column. The use of adeno-associated viruses (AAV) as an effective vector for the delivery of ssDNA in gene therapy, is well established and continues to grow. As with any protein, viral proteins (VPs) are subject to post-translational modifications that can impact stability, capsid assembly, and overall efficacy. As a result, peptide mapping can be used to evaluate the presence and identification of these modifications.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.
