Definition: What is Recombinant Antibody Production?

Recombinant antibodies (rAbs) are monoclonal antibodies which are generated in vitro using antibody coding genes without immunizing any animals or cultivating any hybridomas. This technology involves recovering antibody genes from source cells, amplifying and cloning the genes into an appropriate phage vector, introducing the vector into a host (bacteria, yeast, or mammalian cell lines), and achieving expression of adequate amounts of functional antibody. Recombinant antibodies maintain high standard of specificity and low immunogenicity. Recombinant antibodies are becoming indispensable tools for basic research, diagnostics, and clinical applications.

Recombinant antibodies can be produced in various formats: full-length, scFv, Fab, sdAb/VHH, Fc fusion protein, chimeric, and bispecific antibodies

Every full-length immunoglobulin (IgG) molecule consists of two light and heavy chains connected by disulfide bonds. Recombinant antibodies can come in different formats, including: full-length immunoglobulins (Ig), monovalent antibody fragments such as single-chain fragment variable (scFv) and fragment antigen-binding (Fab), and multimeric formats such as diabodies (dimeric scFvs) or triabodies (trimeric scFvs). Antibody fragments, like scFv, Fab and VHH, are small in size, thereby offering improved penetration of tissues or tumors compared to their full-length counterparts.

Case study: Data of Antibody Production

1. SDS-PAGE

The result of SDS-PAGE under reducing conditions shows that the purity of the antibody is >95%.

2. SEC-HPLC

The result of SEC-HPLC shows that the purity of the antibody is >90%.

3. ELISA
