The benevolent COVID virus has brought our industry many “gifts.” One birthday present is like a jelly of the month club subscription, and it’s impacted all Central Labs and providers of Clinical Sample Collection Kits, without discretion: the shifting un-availability of important kit contents, like vacutainers and polypropylene tubes. While…

What is Hybrid LC-MS/MS? Technically Hybrid LC-MS/MS is a technique that combines an affinity capture step with LC-MS/MS detection. Usually it only requires one antibody, whereas a typical LBA technique will require two. Following affinity capture, it is common to include a digestion step to produce surrogate peptides, which are…

Biomarkers can be defined and utilized for many purposes. There are disease biomarkers as well as mechanistic or pharmacological biomarkers. To reduce attrition and better understand a therapeutic, it is essential to be able to monitor the effectiveness of the therapeutic during drug development. Measurement of biomarker levels related to…
