Application of the Modular Approach to an In-House Validation Study of Real-Time PCR Methods for the Detection and Serogroup Determination of Verocytotoxigenic Escherichia coli4844
serogroup-specific genes have been proposed by the European Reference Laboratory for VTEC (EURL- VTEC) as a technical specification to the European Normalization Committee (CEN TC275 / WG6). Here we applied a “modular ...
Development and validation of a ultra-high-performance liquid chromatography-UV method for the detection and quantification of erectile dysfunction drugs and some of their analogues found in counterfeit medicines.
compared to the registered HPLC method for the assay of Viagra(®) which was considered as the reference method. The method is also compatible with on-line coupling mass spectrometry and will significantly ...
