The development of the hybridoma technology created the possibility to obtain unlimited amounts of monoclonal antibodies (mAb) with high specificity and affinity for any target and to introduce mAbs in a wide range of applications; however, the bulky size of mAbs, costly production, and cumbersome engineering hampered regularly their streamlined development in some applications.  In Single Domain Antibodies: Methods and Protocols, expert researchers examine single variable domain antibody fragments, referred to as VH, VL, VHH or VNAR. These fragments are the smallest intact antigen-binding fragments that can be produced recombinantly at low cost.  Written in the highly successful Methods in Molecular Biology™ series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
