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…

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…
