Single domain antibody (also called domain antibody or sdAb) is an antibody fragment consisting of a single monomeric variable antibody domain andlacking the light chain and CH1 domain of the heavy chain. Like a whole antibody, it is able to bind selectively to a specific antigen. With a molecular weight of only 12–15 kDa, single domain antibodies are much smaller than common antibodies (150–160 kDa), and even smaller than Fab fragments (~50 kDa, one light chain and half a heavy chain) and single-chain variable fragments (~25 kDa).   www.creative-biolabs.com/Nanobody-Single-Domain-Antibody.html
