Protein analysis by desorption electrospray ionization mass spectrometry (DESI-MS) is limited and often accompanied by a mass-dependent loss in sensitivity as protein molecular weight increases. Previously, incomplete dissolution was identified as a potential contributing factor to this limitation for larger proteins. Here, we developed a unique two-step configuration in which a prewetting solvent is applied to the sample surface proximal to DESI analysis by a wetting quill to increase dissolution time and the detection of larger protei
