In Vitro Selection of Single-Domain Antibody (VHH) Using cDNA Display
Single-domain antibody (e.g., Nanobody, VHH antibody) is a promising scaffold for therapeutic and diagnostic reagents. To expand the range of target molecules, in vitro selection using cell-free display technologies such as cDNA display is useful and powerful because of their huge libraries and robust stability. We provide technical details for in vitro selection of single-domain antibodies using cDNA display.
