Previously she had been with Pfizer and legacy companies for over 20 years working in the quantitative LC-MS/MS field. She was one of the early pioneers of using immunoaffinity combined with LC-MS/MS to offer additional selectivity which is now commonly referred to as Hybrid LCMS. She has numerous publications and presentations in her field and recently contributed to a white paper on recommendations for validation of LCMS based bioanalytical methods for protein biotherapeutics.

Immunoaffinity LC-MS/MS or hybrid LC-MS/MS is an approach that has been gaining a lot of traction in the past several years. The technique allows the quantitation of low-level analytes (proteins or peptides in many cases) in biological matrices with exquisite selectivity and sensitivity. Many pharmaceutical companies are trying to expand…

Due to the relative maturity of the technology, most people’s instinct when thinking about bioanalysis of large molecules is towards ligand binding assays. However, we urge people to be open to a more flexible approach. Using hybrid LC-MS/MS can be an equally useful tool for quantitation of biological therapeutics and…

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…
