Mutations in Notch3 cause CADASIL (cerebral autosomal dominant adult onset arteriopathy), which leads to stroke and dementia in humans. CADASIL arteriopathy is characterized by major alterations of vascular smooth muscle cells and the presence of specific granular osmiophilic deposits. Patients carry highly stereotyped mutations that lead to an odd number(More)
The Semliki Forest virus (SFV) vector system is a new approach for in vivo expression of heterologous proteins and can also be used to generate specific immune responses in animal models. HIV-1 envelope glycoprotein produced using the SFV expression system is correctly folded, cleaved, transported to the cell surface and exhibits functional activity. We(More)
BACKGROUND The study was conducted to evaluate the analytical and clinical performance of the VIDAS® 25-OH Vitamin D Total assay. The clinical performance of the assay was compared with four other immunoassays against the results of two different liquid chromatography/mass spectrometry methods (LC-MS/MS) standardized to NIST reference materials. METHODS(More)
Monoclonal antibodies (MAbs) were generated by immunizing mice with a truncated recombinant protein corresponding to the immunodominant region (residues 1-120) of hepatitis C virus (HCV) nucleocapsid protein. The specific recognition by either human sera or mouse monoclonal antibodies of overlapping peptides spanning the core region 1-120 as well as the(More)
BACKGROUND High performance anti-hepatitis E virus (HEV) IgG assays are crucial for epidemiology. OBJECTIVE To evaluate the performance of 2 prototypes developed for the VIDAS® automatic system for detecting anti-HEV IgG, one based on the ORF2 antigen (ORF2 prototype) and the other on the ORF2 and ORF3 antigens (ORF2/3 prototype), with reference to the(More)
BACKGROUND Elucidating the structural basis of antigen-antibody recognition ideally requires a structural comparison of free and complexed components. To this end we have studied a mouse monoclonal antibody, denoted 13B5, raised against p24, the capsid protein of HIV-1. We have previously described the first crystal structure of intact p24 as visualized in(More)
The aim of the present study was to test the antigenicity of alpha-deoxyribonucleotides in order to develop a new tool for the detection of nucleic acid sequences for use in diagnostic applications. We describe four monoclonal antibodies (Mabs) which recognize alpha-deoxyribonucleotides. Two were raised against a poly(alpha-dT) sequence and specifically(More)
VIDAS D-dimer (bioMérieux) is a new quantitative ELISA for D-dimer determination designed for the VIDAS automated system. The test contains single-dose, ready-to-use reagents and is completed within 35 min. Quantitative results are obtained from a calibration curve stored in the software of the system and expressed as fibrinogen equivalent units. The(More)
The relative importance of the host immune response to various antigenic and functional sites on the HN glycoprotein of Sendai (6/94) virus for protection in vivo, was evaluated in mice passively immunized with monoclonal antibodies to HN and then intranasally challenged with infectious virus. Five neutralizing monoclonal antibodies reacting with distinct(More)
