Abstract
Nanobodies are recombinant antigen-specific single domain antibodies (VHHs) derived from the heavy chain-only subset of camelid immunoglobulins. Their small molecular size, facile expression, high affinity, and stability have combined to make them unique targeting reagents with numerous applications in the biomedical sciences. From our work in producing nanobodies to over sixty different proteins, we present a standardised workflow for nanobody discovery from llama immunisation, library building, panning, and small-scale expression for prioritisation of binding clones. In addition, we introduce our suites of mammalian and bacterial vectors, which can be used to functionalise selected nanobodies for various applications such as in imaging and purification. Key features • Standardise the process of building nanobody libraries and finding nanobody binders so that it can be repeated in any lab with reasonable equipment. • Introduce two suites of vectors to functionalise nanobodies for production in either bacterial or mammalian cells.
