Little to LARGE: LC-MS/MS peptide method development for small molecule specialists

The development of LC-MS/MS methods for the quantitation of large molecules within biological matrices can help to overcome some of the challenges associated with immunoassay-based analyses. For example, the need to raise new antibodies against novel analytes, poor specificity due to cross reactivity with similar compounds, and for radioimmunoassays the additional safety considerations. LC-MS/MS method …

Supercharging reagents – revving up peptide LC-MS analyses

Over the past 5 years, LC-MS has (arguably) become the technique of choice to quantify peptides in biological matrices. The benefits of using LC-MS as a quantitative technique are significant, however, there is one drawback – low sensitivity. The acquisition of multiple numbers of charge states for peptides in the MS source can result in …
