Abstract

Sequence analysis of synthetic peptides using Edman chemistry can be very useful for the elucidation of certain types of synthetic problems, such as residue deletions and the presence of common stable derivatives, and for following the progress of the synthesis itself. However, it can also be a relatively poor technique for assessing quantitative aspects and the type and degree of adduct formation that arise from the synthetic chemistry. For these latter considerations, techniques such as mass spectrometry can often give more precise and informative data about the integrity of a synthetic peptide. Thus, sequence analysis is best applied judiciously and then used in combination with other methods. Furthermore, proper interpretation of the results of sequence analysis of synthetic peptides relies on a thorough knowledge of the sequencing process.
