✦ Synopsis

Cytochrome c and myoglobin were subjected to sodium dodecyl sulphate (SDS) polyacrylamide gel electrophoresis, electroeluted from the gel and fragmentated with cyanogen bromide. High-performance liquid chromatographic (HPLC) separation of the peptide mixtures obtained was improved when using a gradient of acetonitrile containing phosphates in comparison with a gradient containing trifluoroacetic acid. This finding may be useful for the HPLC analysis of peptides derived from SDSprotein complexes.
