Lonza’s BEGM™ medium and the Growth Media portion of Lonza’s B-ALI BulletKit™ Medium are essentially the same and can be used interchangeably (for example, cells could be cultured in Lonza’s BEGM™ medium just prior to differentiation using the Differentiation Media portion of Lonza’s B-ALI BulletKit™ Medium).

Please note that, for maximum differentiation, Lonza suggests minimal expansion of cells prior to ALI differentiation. Lonza’s B-ALI BulletKit™ Medium is designed to provide sufficient Growth Media for thawing, plating, and expanding the cells through one passage prior to differentiation (the maximum amount of expansion that is guaranteed prior to differentiation), hence, if using Lonza’s ALI screened cells and ALI differentiation media, there should be no need to also purchase Lonza’s BEGM™ medium.
