Proteomics Phospho Kit
Phosphoproteomics has matured into a strong technology for the simultaneous detection of phosphopeptides in complex samples. However, phosphoproteomics workflows consist of several steps that all need to be controlled carefully (Urban, J., Analytica Chimica Acta 2021, 338857). If phosphoproteomics is performed in a targeted fashion, HPLC retention time (RT) windows for the selected proteotypic phosphopeptides need to be established carefully, as RTs are not easily transferable between instruments.
Benefits of Proteomics Phospho Kit
- Non-naturally occurring peptides (allowing application in biological samples)
- Non-isotopically labeled peptides (facilitating inclusion into database searches)
- Broad LC gradient coverage
- Stable RTs across multiple injections
- Use for column performance evaluation
- Use for optimization of LC-MS gradients
