A specific camel VHH (variable domain of dromedary heavy chain antibody) fragment was used to crystallize the intrinsically flexible addiction antidote MazE. Only 45% of the polypeptide chain is found ordered in the crystal. The MazE monomer consisting of two beta-hairpins connected by a short alpha-helix has no hydrophobic core on its own and represents only one half of a typical protein domai...

The application of long-chained peptides (+30 aa) and relatively short proteins (<300 has experienced an increasing interest in recent years. However, a reliable production platform is still missing since manufacturing challenged by inherent problems such as mis-folding, aggregation, low yields. And neither chemical synthesis nor available recombinant approaches are effective efficient. ...

Two ampicillin-resistant (Amp(r)) isolates of Vibrio harveyi, W3B and HB3, were obtained from the coastal waters of the Indonesian island of Java. Strain W3B was isolated from marine water near a shrimp farm in North Java while HB3 was from pristine seawater in South Java. In this study, novel beta-lactamase genes from W3B (bla(VHW-1)) and HB3 (bla(VHH-1)) were cloned and their nucleotide seque...

BACKGROUND Optical molecular imaging is an emerging novel technology with applications in the diagnosis of cancer and assistance in image-guided surgery. A high tumour-to-background (T/B) ratio is crucial for successful imaging, which strongly depends on tumour-specific probes that rapidly accumulate in the tumour, while non-bound probes are rapidly cleared. Here, using pre-invasive breast canc...

As part of research exploring the feasibility of using antibody fragments to inhibit the growth of organisms implicated in dandruff, we isolated antibody fragments that bind to a cell surface protein of Malassezia furfur in the presence of shampoo. We found that phage display of llama single-domain antibody fragments (VHHs) can be extended to very harsh conditions, such as the presence of shamp...
