Ascites (In-Vivo) Production

In Vivo Production

Monoclonal antibody is produced in vivo in ascites fluid. Production in ascites fluid is nearly always the most economical method of monoclonal antibody production; your cost per milligram of monoclonal antibody is the lowest. Monoclonal antibody produced in ascites fluid is typically purified before shipment. For monoclonal antibodies produced repeatedly in large quantities, SDIX offers an ascites optimization process to maximize production efficiency and minimize animal use.

All incoming cell lines require pre-production verification.

Includes:

     

  • Viability check of cell line
  • Isotype Testing
  • Strains: Balb/c, ICR SCID, CAF1 are available, please contact us for additional strains
  • Lot Size 10 -2000 mice per lot (> 500 mice needed, please call for availability)
  • Ascites fluid is harvested over multiple taps
  • At completion all taps are pulled and centrifuged
  • Final IgG concentration is determined
  • Final product stored at -20oC
  • Average ascites volume per mouse is 3-5mls/mouse and average antibody concentration is 3-5mg/mL.
  • Timing 2-3 months

Optional Services

     

  • Limited Dilution Cloning (Verify monoclonality of cell line)
  • Mycoplasma testing
  • Murine pathogen testing Mouse parvo virus
    • Mouse hepatits virus
    • Pneumonia virus
    • Sendai virus
    • Minute virus
