Minimum amount of material needed for analysis:

Technique Minimum needed
MALDI protein  1 pmol
MALDI peptide 50 fmol
ESI MS small molecule  1 pmol
HPLC separation 10 ug
2D gel 50 ug
2D DIGE 100 ug
LC MS/MS 50 fmol*
Orbi trap LC MS/MS complex mixture 300-400 ng
MudPIT 10-30 ug

*50 fmol is the detection limit for the standard (tryptic digest of BSA), more material is needed for most analyses particularly for detection of modifications, e.g. phosphorylation sites.
