A spinnable and automatable StageTip for high throughput peptide desalting and proteomics
The stop-and-go-extraction tips (StageTips) have been widely used in shotgun proteomics to clean/desalt peptide samples prior to LC-MS/MS analysis. Here, an extremely simple and high throughput StageTip protocol is described. In this protocol, an adaptor is introduced to the StageTip, and makes it readily available for bench-top centrifugation. Each spin step (with 200 μL buffer loaded) takes around 2 min at 4,000 rpm. Compared with previous syringe-based manual pressure device, the spinnable StageTip is completely labor-free, automatable, and can be easily scaled up. Considered with the recently developed 96FASP method, the spinnable StageTips provide another component to the high throughput workflow for clinical proteomics and biomarker discoveries.
