Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Upstream Processing01:27

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Area of Science:

  • Biotechnology
  • Bioprocess Engineering
  • Cell Culture Technology

Background:

  • Hybridoma cell culture is crucial for monoclonal antibody production.
  • Optimizing bioreactor conditions is essential for maximizing antibody yield.
  • Understanding cell growth kinetics informs process improvements.

Purpose of the Study:

  • To optimize bench-scale hybridoma cell culture for enhanced monoclonal antibody production.
  • To investigate the effects of perfusion, potassium acetate, and nutrient fortification on cell density and antibody concentration.

Main Methods:

  • Utilized a perfusion culture mode in a bioreactor.
  • Supplemented the culture medium with potassium acetate.
  • Fortified the medium with essential nutrients, including amino acids and vitamins.

Main Results:

  • Perfusion culture at 1/2 working volume yielded 11 x 10(5) cells/ml and 28 mg/L antibody.
  • Supplementation with 1 g/L potassium acetate increased antibody production to 38 mg/L.
  • Nutrient fortification raised cell density to 42 x 10(5) cells/ml and antibody concentration to 94 mg/L.

Conclusions:

  • Perfusion culture, potassium acetate supplementation, and nutrient fortification are effective strategies for optimizing hybridoma bioreactor performance.
  • These combined methods significantly enhance both viable cell density and monoclonal antibody production.
  • The optimized process demonstrates a scalable approach for efficient antibody manufacturing.
