Recent years have seen great upward leaps in the development of mass spectrometry applied to the field of proteomics. Today it is possible to take a complex biological sample such as organelles, cells, tissue or a biofluid, perturbed or stimulated in some way, and identify and quantitate up to several…
Testing cleaning validation samples requires a validated method. The extent of validation is dependent upon the type of method employed, the capabilities of the method, the scientific and regulatory needs of the resulting data and the anticipated outcome of the testing. A number of test method options are reviewed for…
