Creative Biolabs is one of the well-recognized experts who are professional in in vitro diagnostics (IVD) antibody development against various markers. Now we are glad to provide the custom IVD recombinant antibody discovery service for our customers all over the world.
Introduction of Recombinant Antibody
The recombinant antibody is antibody fragments encoded by recombinant coding genes. Compared with classical antibodies, recombinant antibodies present a series of advantages in both medical and research applications which including rapid tissue penetration, ease of engineering and manufacture, broader biodistribution, and rapid clearance from blood. Moreover, we can control the antibody type by controlling the DNA sequence. In general, the recombinant antibody contains Fv, Fab, Fc, scFv, and sdAb.

Antibody Affinity Maturation
Affinity maturation is the process to improve antibody affinity for an antigen both in vivo and in vitro. With extensive experience, now we can provide two antibody affinity maturation methods, untargeted mutagenesis, and oligonucleotide-directed mutagenesis, for the construction of defined or random sub-libraries to introduce a large number of mutants of the original antibody. The subsequent stage is library screening, here two screening strategies are available which are “surface-panning” strategy and “solution-sorting” strategy. Moreover, we can also provide the antibody affinity measurement service.
Recombinant Antibody Reformatting
Antibody reformatting is the process to obtain soluble antibody fragments or full monoclonal antibodies from the antigen binding regions of an antibody. Apart from the Fc portion, the reformatting of variable region results in a variety of different fragments such as scFv, Fab, sdAb, and BsAb. What’s more, we can even re-engineer the antibodies into virtually any format to meet our clients’ special needs.
