Reversed-phase isolation of peptides.
In reversed-phase HPLC, peptides are separated on a hydrophobic stationary phase and eluted with a gradient of increasing organic solvent concentration. Protocols describing the separation of peptides in 5- to 500-pmol quantities via narrow-bore (2-mm-i.d.) or microbore (1-mm-i.d.) columns, as well as for the separation of peptides in quantities <5 pmol are provided in this unit. Capillary HPLC columns require a gradient flow rate of 3 to 5 omponents present in a small sample prior to automated sequencing is possible via the procedures for matrix-assisted laser desorption/ionization (MALDI) mass spectrometry and capillary electrophoresis.
