NaLi-H1
ǂa ǂuniversal synthetic library of humanized nanobodies providing highly functional antibodies and intrabodies
Abstract
In vitro selection of antibodies allows to obtain highly functional binders, rapidly and at
lower cost. Here, we describe the first fully synthetic phage display library of humanized llama
single domain antibody (NaLi-H1: Nanobody Library Humanized 1). Based on a humanized synthetic
single domain antibody (hs2dAb) scaffold optimized for intracellular stability, the highly diverse
library provides high affinity binders without animal immunization. NaLi-H1 was screened following
several selection schemes against various targets (Fluorescent proteins, actin, tubulin, p53, HP1).
Conformation antibodies against active RHO GTPase were also obtained. Selected hs2dAb were
used in various immunoassays and were often found to be functional intrabodies, enabling tracking
or inhibition of endogenous targets. Functionalization of intrabodies allowed specific protein
knockdown in living cells. Finally, direct selection against the surface of tumor cells produced
hs2dAb directed against tumor-specific antigens further highlighting the potential use of this
library for therapeutic applications.
