Abstract: The disclosure is directed to a method for seed train expansion of adherent cells comprising culturing cells with a serum-supplemented growth medium in a N-2 vessel; removing the cells from the serum-supplemented medium; inoculating the cells from step into a serum-free growth medium in a N-1 vessel; culturing the cells in the N-1 vessel under suspension conditions; and inoculating a growth medium in a bioreactor with the suspension-cultured cells. In some aspects, the adherent cells are not suspension-adapted. In some aspects, the adherent cells are suspension-adapted. In some aspects, the adherent cells produced by the seed train expansion method are used to produce viral vectors. In some aspects, the viral vectors are AAV vectors.

Abstract: Provided are methods to characterize the VP1, VP2 and VPS capsid proteins in an adeno-associated virus (AAV) particle using liquid chromatography mass spectrometry, and/or ultraviolet (UV)-visible spectroscopy. The methods generally include the steps of (a) subjecting an AAV particle to liquid chromatography to denature and then separate the VP1, VP2 and VPS capsid proteins, and (b) subjecting the separated VP1, VP2 and VPS capsid proteins produced in step (a) to UV and mass spectrometry to determine the ratio and masses of the VP1, VP2 and VPS capsid proteins in the AAV particle. In another aspect, the disclosure provides an AAV composition comprising a post-translation modification. The disclosure also provides methods for characterizing the purity of AAV compositions using liquid chromatography mass spectrometry.
