Hybridoma Technology

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.

Synthesized amphiphilic polyethylene glycol-lipid polymers conjugated to specific DNA sequences (polyDNA).
Functionalized cell surfaces and substrate surfaces with these polyDNA-PEG-lipid conjugates.
Mediated cell-cell and cell-substrate attachments through complementary DNA hybridization.
Monitored the attachment processes using fluorescence microscopy.

Main Results:

Successfully transferred polyDNA-PEG-lipid conjugates to cell surfaces via incubation.
Demonstrated specific cell-cell and cell-substrate attachments mediated by DNA hybridization.
Visualized and confirmed the controlled attachments using fluorescence microscopy.

Conclusions:
