    • www.proteocell.com3 KEYS TO EFFECTIVE BIOPROCESS FOR BIOPHARMA MANUFACTURING1) Superior cell line and cell line technology used;2) Efficient and effective bioprocess development;3) A-Z adequate regulatory compliance.
    • www.proteocell.comBIOPROCESS INTEGRATION STRATEGY OF PROTEOCELL SSI1) Cell Line Engineering:•Using the latest in Ab molecular engineering methods to design a DNA expression vectorsystem that is stable and high producing, and scalable to a production system (bioreactorscale)2) Process Development:• Preliminary bioprocess work that ProteoCell has successfully incorporated into its cell lineengineering strategy by overlapping clonal selection concepts with Process Developmentconcepts;• It includes the preliminary expression of the designed Ab clones in a quasi-production/fullproduction setting to test for product homogeneity and stability—before final clonal selectionand cell banking;• This includes production in a bioreactor, simulating production batch conditions, includingchemically defined media and other regulatory compliant bioprocess conditions.
    • www.proteocell.comMOLECULAR ENGINEERING HIGHLIGHTS OF PROTEOCELL SSI SYSTEM1) Alternate “tagging-targeting vector” mechanism for rapid generationof stable genomic integration of target gene sequence;2) Strong CMV promoter drives LC or HC expression;3) Weaker promoter or IRES drives selectable marker to ensure thatMAb expression is dominant;4) Single or double fluorescence tagging of protein sequence dependingon experimental design strategy.
