Nanobodies are recombinant, antigen-specific, single-domain, variable fragments of camelid heavy chain-only antibodies. The innate supremacy of nanobodies as a renewable source of affinity reagents, together with their high production yield in a broad variety of expression systems, minimal size, great stability, reversible refolding and outstanding solubility in aqueous solutions, and ability t...

The discovery of naturally occurring, heavy-chain only antibodies in Camelidae, and their further development into small recombinant nanobodies, presents attractive alternatives in drug delivery and imaging. Easily expressed in microorganisms and amenable to engineering, nanobody derivatives are soluble, stable, versatile, and have unique refolding capacities, reduced aggregation tendencies, an...

Post-translational modifications are difficult to visualize in living cells and are conveniently analyzed using antibodies. Single-chain antibody fragments derived from alpacas and called nanobodies can be expressed and bind to the target antigenic sites in living cells. As a proof of concept, we generated and characterized nanobodies against the commonly used biomarker for DNA double strand br...
