Development of a monoclonal antibody sandwich ELISA for the determination of antigen content and quality in diphtheria vaccines.
different human vaccine products. We demonstrate the ability of the assay to discriminate between batches of different content and quality using vaccine batches that were prepared to contain differing amounts ...
Application of a strain-level shotgun metagenomics approach on food samples: resolution of the source of a Salmonella food-borne outbreak
200 students and teachers. Following standard procedures, the Belgian National Reference Center for human salmonellosis and the National Reference Laboratory for Salmonella in food and feed used ...
Towards Real-Time and Affordable Strain-Level Metagenomics-Based Foodborne Outbreak Investigations Using Oxford Nanopore Sequencing Technologies
serotyped. This was achieved by applying a bioinformatics method on the long reads using reference-based classification. The same result could be obtained after 24-h sequencing on the more recent lower output ...
Establishment of a biological reference preparation for Hepatitis A Vaccine (Inactivated, Non-adsorbed)4425
3 manufacturers as candidate Biological Reference Preparations (BRP s). Thirteen laboratoriesparticipated in the collaborative study. They were asked to use an in vitro ELISA method adapted from ...
Collaborative study for the standardisation of the histamine sensitizing test in mice and the CHO cell-based assay for the residual toxicity testing of acellular pertussis vaccines.1
study, a potency of 7500 IU /vial (International Units per vial) was assigned to the current Ph. Eur. Biological Reference Preparation (BRP) for PT. The results of the study also show that 1) intra- and ...
Establishment of the Ph. Eur. BRP for Varicella Vaccine Batch 1227
manufacturers was carried out to establish a common reference material for this purpose and establish a Ph. Eur. Biological Reference Preparation. Two candidate reference preparations (X and Y), obtained from ...
Establishment of the Ph. Eur. BRP for varicella vaccine batch 1.
to establish a common reference material for this purpose and establish a Ph. Eur. Biological Reference Preparation. Two candidate reference preparations (X and Y), obtained from 2 different EU ...
Validation of the CALUX bioassay for PCDD/F analyses in human blood plasma and comparison with GC-HRMS.
bioassay for biological sample analysis and to compare toxic equivalency (TEQ) values obtained by the reference GC- HRMS technique and by the screening method. This article focuses on the validation results ...
Impact of DNA extraction on whole genome sequencing analysis for characterization and relatedness of Shiga toxin-producing Escherichia coli isolates.
Nextera XT library preparation; (ii) MiSeq sequencing (data quality, read mapping against plasmid and chromosome references); and (iii) WGS data analysis, i.e. isolate characterization (serotyping, ...
