objective(s): as t-cell immunoglobulin and mucin domain 3 (tim-3) is an immune regulatory molecule; its blocking or stimulating could alter the pattern of immune response towards a desired condition. based on the unique features of nanobodies, we aimed to construct an anti-tim-3 nanobody as an appropriate tool for manipulating immune responses for future therapeutic purposes. materials and meth...
Owing to peculiar properties of nanobody, including nanoscale size, robust structure, stable and soluble behaviors in aqueous solution, reversible refolding, high affinity and specificity for only one cognate target, superior cryptic cleft accessibility, and deep tissue penetration, as well as a sustainable source, it has been an ideal research tool for the development of sophisticated nanobiot...
Objectives Nanobodies, the single domain antigen binding fragments of heavy chain-only antibodies occurring naturally in camelid sera, are the smallest intact antigen binding entities. Their minimal size assists in reaching otherwise largely inaccessible regions of antigens. However, their camelid origin raises a possible concern of immunogenicity when used for human therapy. Humanization is a ...
Nanobodies are highly valuable tools for numerous bioanalytical and biotechnical applications. Here, we report the characterization of a nanobody that binds a short peptide epitope with extraordinary affinity. Structural analysis reveals an unusual binding mode where the extended peptide becomes part of a β-sheet structure in the nanobody. This interaction relies on sequence-independent backbon...

Bovine viral diarrhea-mucosal disease (BVD-MD) is caused by bovine viral diarrhea virus (BVDV), and results in abortion, stillbirth, and fetal malformation in cows. Here, we constructed the phage display vector pCANTAB 5E-VHH and then transformed it into Escherichia coli TG1-competent cells, to construct an initial anti-BVDV nanobody gene library. We obtained a BVDV-E2 antigen epitope bait prot...
UNLABELLED Nanobodies are approximately 15-kDa proteins based on the smallest functional fragments of naturally occurring heavy chain-only antibodies and represent an attractive platform for the development of molecularly targeted agents for cancer diagnosis and therapy. Because the human epidermal growth factor receptor type 2 (HER2) is overexpressed in breast and ovarian carcinoma, as well as...
Efficient production of nanobodies against urease activity ofHelicobacter pylori in Pichia pastoris.
BACKGROUND/AIM Helicobacter pylori is a major health problem. One of the therapeutic approaches is administration of antibody against H. pylori. The methylotrophic Pichia pastoris is a suitable host for expression of recombinant antibody fragments. The aims of this study were the expression and the evaluation of camelid nanobody in the yeast Pichia pastoris. MATERIALS AND METHODS The camelid-...
