Offline Micro-IMAC Enrichment of Phosphoproteins.

CSH protocols

Corthals GL, Wasinger VC, Goodlett DR.
PMID: 21356966
CSH Protoc. 2007 Nov 01;2007:pdb.prot4624. doi: 10.1101/pdb.prot4624.

INTRODUCTIONImmobilized metal affinity chromatography (IMAC) can be performed offline or online with μLC-ESI-MS/MS. The online configuration has been used successfully despite suboptimal low-level analysis due to the relative disparity between IMAC and μLC flow rates. With IMAC performed offline...
