Efficient Expression of Antibody Fragments with the Brevibacillus Expression System
Antibodies, owing to their capability to bind specifically to a target molecule, have been and will continue to be applied in various areas, including research, diagnosis and therapy. In particular, antibody fragments, which are size-reduced antibodies comprising functional variable domains, are suited for production in bacteria. They also are useful in applications requiring intracellular deli...
متن کاملIntegrative expression system for delivery of antibody fragments by lactobacilli.
A series of expression cassettes which mediate secretion or surface display of antibody fragments was stably integrated in the chromosome of Lactobacillus paracasei. L. paracasei producing surface-anchored variable domain of llama heavy chain (VHH) (ARP1) directed against rotavirus showed efficient binding to rotavirus and protection in the mouse model of rotavirus infection.
متن کاملExpression of antibody fragments by periplasmic secretion in Escherichia coli.
Antibody-based drugs are increasingly used in the clinic, and their importance is set to escalate in the coming years as more drugs in this class progress through clinical trials. Although many such drugs utilize whole antibodies, others exploit fragments, e.g., fragment antigen binding (Fab') or single-chain fragment variable (scFv), which retain the antigen-binding specificity without the fra...
متن کاملSystematic screening of soluble expression of antibody fragments in the cytoplasm of E. coli
BACKGROUND Disulfide bonds are the most common structural, post-translational modification found in proteins. Antibodies contain up to 25 disulfide bonds depending on type, with scFv fragments containing two disulfides and Fab fragments containing five or six disulfide bonds. The production of antibody fragments that contain native disulfide bonds can be challenging, especially on a large scale...
متن کاملA Comparative Investigation of the Bispecific Antibody: Expression in Expi293F Cells and E.Coli
Aims: Bispecific antibodies are capable of targeting two cell surface markers simultaneously. Blinatumomab an anti-CD3/CD19 Bispecific T cell engager antibody (BiTE) is approved for clinical application by FDA. This BiTE effectively targets malignant cells in ALL (Acute Lymphoblastic Leukemia) patients. For production of large quantities of such antibodies in industrial settings choice of host ...
