Abstract

Publisher Summary This chapter primarily aims to explore sequencing strategies capable of rapid analysis of proteins, possibly recovered from 2D-electrophoresis gels. For this purpose, the chemistry needed to be adaptable to multiple samples and sensitive enough to work in the femtomole range. The isothiocyanate trifluoroethyl isothiocyanate (TFEITC) chemistry shows early signs of meeting these criteria. The main practical requirement is that the starting peptide is dissolved in a defined volume of coupling buffer, dependent only on the number of cycles required and the volume applied per cycle. The chapter explains, on a low-picomolar scale, that a phosphorylated tyrosine residue could be directly identified making this a potentially powerful tool for the identification of this and other sites of post-translational modification. The inherent simplicity of the process should also allow for easy automation to permit rapid processing of samples in parallel. Certain limitations are entirely instrument-related, and not relevant to the demonstration of the degradation chemistry; however, future developments in instrumentation are required to overcome these limitations.
