We describe the rapid isolation of single-domain recombinant antibodies in VHH format from a pre-immune llama library created in our laboratory. Such naïve library has demonstrated to be a versatile tool and enabled the isolation of several different antibodies for any of the six proteins panned in parallel. The binders specific for human fibroblast growth(More)

Single-domain antibodies in VHH format specific for fibroblast growth factor receptor 1 (FGFR1) were isolated from a phage-display llama naïve library. In particular, phage elution in the presence of the natural receptor ligand fibroblast growth factor (FGF) allowed for the identification of recombinant antibodies that compete with FGF for the same region(More)
Mutations in the nucleophosmin 1 (NPM1) gene are the most frequent genetic aberrations of acute myeloid leukemia (AML) and define a clinically distinct subset of AML. A monoclonal antibody (T26) was raised against a 19-amino acid polypeptide containing the unique C-terminus of the type A NPM1 mutant protein. T26 recognized 10 of the 21 known NPM1 mutants,(More)
Antibodies are indispensable reagents in basic research, and those raised against tags constitute a useful tool for the evaluation of the biochemistry and biology of novel proteins. In this paper, we describe the isolation and characterization of a single-domain recombinant antibody (VHH) specific for the SNAP-tag, using Twist2 as a test-protein. The(More)
Histone deacetylases (HDACs) are modification enzymes that regulate a plethora of biological processes. HDAC1, a crucial epigenetic modifier, is deregulated in cancer and subjected to a variety of post-translational modifications. Here, we describe the generation of a new monoclonal antibody that specifically recognizes a novel highly dynamic prophase(More)
BACKGROUND Cre recombinase is a common reagent used for the in vivo on/off switching of the expression of target genes flanked by loxP sites. In particular, recombinant TAT-Cre fusion constructs purified from bacteria have been used to promote the cell uptake of the enzyme. However, the recovery of active TAT-Cre remains a demanding process and its specific(More)
