An Improved Immunoaffinity LC-MS/MS Workflow for the Quantitation of IgG's during Preclinical PK Studies

The testing of biotherapeutic proteins (particularly IgG's) in animals is a requirement for approval by regulatory agencies, prior to treatment in humans. PK/PD studies of biotherapeutic protein metabolism have traditionally been performed using ELISA. However, the use of immunoaffinity purification coupled with LC-MS/MS has proven advantageous in part due to its ability to monitor total drug and multiple surrogate peptides. As the number of biotherapeutic proteins in the pipeline increases, so does the need for an optimized workflow. Toward this end, we have developed an optimized workflow which improves the dynamic range of the assay, decreases the digestion time, and increase the overall workflow flexibility. The assay is also compatible with automation.
