Tissue and Non-Liquid Matrices (such as cell lines, red blood cells, PBMCs, bone marrow aspirates, and suspension cells) are valuable matrices[] to test for biomarkers (PD) and drug levels (PK). Testing of tissues and…

A recent trend observed at KCAS is that the bioanalytical needs of our clients’ projects are becoming more complex.  There is increasing focus on monitoring delivery of therapeutics to the target of interest. This…

There has been an increasing focus on large molecule therapeutics and pharmaceutical companies have increasingly aligned their development pipelines in that direction. This has resulted in more biological therapeutics coming to market.  Last year,…

Pharmacodynamics (PD) is defined as the study of the biochemical and physiological effects of drugs and the mechanisms of their actions. Where pharmacokinetics looks at how the organism processes the drug, pharmacodynamics studies how…

To read part one of this 2-part series, click here. With increasing focus on large molecule therapeutics and interest in large molecule biomarkers it’s essential to have LC/MS available as a complimentary technology to ligand…

Drug discovery is an essential part of the drug development process. Testing in drug discovery is the mechanism to provide drug candidates that are selected for regulated animal studies and hopefully moving into clinical trials.

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…

I have been studying Biological Markers (biomarkers) for over 25 years, but last 5 years they have exploded and become a key bioanalytical component to a drug’s success. Biomarkers are used to support drug…

The workflow for bioanalytical LC-MS/MS requires isolation of analytes of interest from biological samples prior to analysis. This usually involves an extraction procedure ahead of injection into the LC-MS/MS system where the target compounds…

A recent trend in the pipelines of pharmaceutical companies & biotechs has been a shift to large molecule therapeutics. This presents a challenge for bioanalysis by LC/MS because the molecular weights of the target…

Join us Tuesday November 10, 2020 at 11am EST| 8am PST| 4pm CET| 5pm CET Bioanalytical liquid chromatography­–mass spectrometry (LC–MS) for small molecules is often referred to as a routine technology. That perception may be true for many drugs, but as pharmaceutical companies move into new areas, more  projects may…

Dose Formulation Analysis is an essential step in regulated nonclinical studies to ensure correct doses are administered to underpin toxicokinetic assessments. Based on years of experience, KCAS has built a stand-alone team dedicated to…
