A novel bacteriophage lambda vector system was used to express in Escherichia coli a combinatorial library of Fab fragments of the mouse antibody repertoire. The system allows rapid and easy identification of monoclonal Fab fragments in a form suitable for genetic manipulation. It was possible to generate, in 2 weeks, large numbers of monoclonal Fab(More)
GODIVA (Grid for Ocean Diagnostics, Interactive Visualization and Analysis) is one of the NERC e-Science projects focusing particularly on data analysis via visualization. The data analyzed in GODIVA comes from high-resolution global models of the ocean and atmosphere, thus datasets are large and there are many datasets in a time sequence. We describe the(More)
Photoaffinity labeling with bovine rhodopsin using a retinal with a fixed 11-cis-ene cross-linked exclusively to Trp-265/Leu-266 in helix F, showing that the beta-ionone C-3 is close to helix F. Moreover, since these labeled amino acids are in the middle of helix F, while the Schiff-base linkage to Lys-296 at the other terminus of the chromophore is also in(More)
BACKGROUND The diagnosis of human African trypanosomiasis (HAT) caused by Trypanosoma brucei gambiense relies mainly on the Card Agglutination Test for Trypanosomiasis (CATT). There is no immunodiagnostic for HAT caused by T. b. rhodesiense. Our principle aim was to develop a prototype lateral flow test that might be an improvement on CATT. (More)
Animal African Trypanosomosis (AAT) presents a severe problem for agricultural development in sub-Saharan Africa. It is caused by several trypanosome species and current means of diagnosis are expensive and impractical for field use. Our aim was to discover antigens for the detection of antibodies to Trypanosoma congolense, one of the main causative agents(More)
Trypanosoma vivax is one of the causative agents of Animal African Trypanosomosis in cattle, which is endemic in sub-Saharan Africa and transmitted primarily by the bite of the tsetse fly vector. The parasite can also be mechanically transmitted, and this has allowed its spread to South America. Diagnostics are limited for this parasite and in farm settings(More)
