Recombinant Antibody Development

Recombinant antibodies are monoclonal antibodies constructed in vitro using recombinant DNA technology and produced without restrictions from the immune system. Our company has long-term devoted to the production and purification of recombinant antibodies. We are pleased to use our extensive experience and advanced recombinant antibody development platform to offer the best service for rare disease therapy research and development.

Introduction to Recombinant Antibody

Recombinant antibodies are monoclonal antibodies, including scFv fragments, Fab fragments, chimeric antibodies, and bispecific antibodies. The production of recombinant antibodies involves in vitro genetic manipulation. After cloning the antibody gene into the expression vector, it is transfected into the appropriate host cell line for antibody expression. There are currently three types of recombinant antibodies: naive, synthetic, and immune.

Phage display improved the efficiency of antibody production. An increasing number of recombinant production systems including gram-negative and positive bacteria, insect cell lines, yeast and filamentous fungi, and mammalian cells to transgenic plants and animals have been developed, among which, mammalian cell lines are most commonly used for the production of recombinant antibodies.

Advantages of Recombinant Antibody

  • High repeatability
    Recombinant antibodies are produced from specific genes, so antibody production is controllable.
  • Reduced production time
    After the antibody library is established, the production cycle for recombinant antibodies is 8 weeks.
  • High sensitivity and specificity
    Using recombinant technology, antibody specificity and sensitivity are more easily improved through antibody engineering.
  • Animal-free production
    Recombinant antibodies derived from synthetic or human antibody libraries.
