Protein identification using 20-minute Edman cycles and sequence mixture analysis.
We have developed a 20-min Edman cycle and a multiple sample horizontal flow reactor for the sequence analysis of PVDF-electroblotted proteins. The 20-min cycle uses a 12-min C18 phenylthiohydantoin separation. This cycle and separation is compatible with most Applied Biosystems sequencers. Using this rapid cycle, 10 residues on six different proteins can be completed within a 24-h period. We also demonstrate the use of an algorithm that can sort mixture sequences derived from PVDF bands that contain coeluting proteins.
