Waters Corp WATERS CORPORATION Phosphopeptide Enrichment Kit, 96-well, SPE
The MassPREP™ Phosphopeptide Enrichment Kit is designed for the selective enrichment of phosphopeptides from complex samples. It includes a 96-well micro-scale solid-phase extraction (SPE) plate packed with an affinity sorbent and a unique chemical (Enhancer™) to improve selectivity. This method simplifies phosphopeptide enrichment by not requiring pre-loading the sorbent with a metal chelator, unlike immobilized metal affinity chromatography (IMAC) technology.
- Includes a 96-well micro-scale solid-phase extraction (SPE) plate.
- Uses an affinity sorbent.
- Includes Enhancer™ for improved selectivity.
- Does not require pre-loading the sorbent with metal chelator.
