This is the first floor of BTEC. As we enter through the doors we step into the Lobby which we have not touched, The drug substance moves from the Production suite into the Harvest, Protein A, Viral inactivation, CEX, AEX , viral filtration and bulk fill suites. All this movement is sequential and follows all the cGMP flows and regulations by the FDA.
