Organism TypeHamsterThe gene amplification techniques have been used for production of glycoprotein in recombinant mammalian cell cultures. In these techniques, the dihydrofolate reductase (dhfr) gene amplification system in Chinese Hamster Ovary (CHO) cell line CHO DG44 is most available. CHO DG44 cell line is dihydrofolate reductase negative (dhfr-).
