Nanobody Discovery Details

Nanobodies are the small (15 kDa) and stable single-domain fragments harboring the full antigen-binding capacity of camelid heavy chain–only antibodies. Nanobodies are exquisite chaperones for crystallizing membrane proteins, multiprotein assemblies, transient conformational states and intrinsically disordered proteins. Nanobodies can also be used for other applications in structural biology. Domain-specific Nanobodies have been used in single-particle electron microscopy (EM) to track these domains in particle projections. Because Nanobodies can be functionally expressed as intrabodies in eukaryotic cells, these single-domain antibodies can also be used to track their targets inside a living cell. 

Requirements: Only small amounts (<2mg) of the folded and quality controlled protein are required to produce Nanobodies that recognize conformational epitopes on the native proteins. In case no purified antigen is available, cells expressing purified protein or genetic vaccination may be used to induce an in vivo matured humoral response.
