Project description:DDA analysis of samples of commercial tryptic peptides of BSA which had been either untreated ("original"), conjugated with the Harnimarta et al sequencing reagent ("conj") or conjugated and exposed to alkaline cleavage conditions ("seq"). Data was searched in Proteome Discoverer 2.5 using a 58.017 Da for the sequencing reagent dynamic modification. The associated BSA2 fasta includes a synthetic sequence to generate in silico tryptic peptides representing the original BSA tryptic peptides lacking a single N-terminal amino acid.
