Guanidination of Tryptic Peptides without Desalting for MALDI-TOF MS Analysis

Derivatizations that enhance mass spectral quality often require desalting which presents as a bottleneck in MALDI-TOF MS-proteomics. Guanidination, which converts lysine to homoarginine, an arginine analog, can increase detection of those peptides 5 – 15-fold. Our aim was to improve guanidination b...
