Binding activities of a repertoire of single immunoglobulin variable domains secreted from Escherichia coli
TLDR
Isolated variable domains may offer an alternative to monoclonal antibodies and serve as the key to building high-affinity human antibodies and the name 'single domain antibodies (dAbs)' is suggested for these antigen binding demands.Abstract:
IN antibodies, a heavy and a light chain variable domain, VH and VL, respectively, pack together and the hypervariable loops on each domain contribute to binding antigen1–4. We find, however, that isolated VH domains with good antigen-binding affinities can also be prepared. Using the polymerase chain reaction5, diverse libraries of VH genes were cloned from the spleen genomic DNA of mice immunized with either lysozyme or keyhole-limpet haemocyanin. From these libraries, VH domains were expressed and secreted from Escherichia coli. Binding activities were detected against both antigens, and two VH domains were characterized with affinities for lysozyme in the 20 nM range. Isolated variable domains may offer an alternative to monoclonal antibodies and serve as the key to building high-affinity human antibodies. We suggest the name 'single domain antibodies (dAbs)' for these antigen binding demands.read more

Improved M13 phage cloning vectors and host strains: nucleotide sequences of the M13mp18 and pUC19 vectors
TL;DR: New Escherichia coli host strains have been constructed for the E. coli bacteriophage M13 and the high-copy-number pUC-plasmid cloning vectors and mutations introduced into these strains improve cloning of unmodified DNA and of repetitive sequences.
