title: The use of DODT as a non-malodorous scavenger in Fmoc-based peptide synthesis.
abstract: We have synthesized a random group of peptides and performed cleavages using various cleavage cocktails including 3,6-dioxa-1,8-octanedithiol (DODT). Purity of the peptides was compared to that obtained with standard protocols for cleavage using RP-HPLC and Maldi-Tof mass spectrometry. We show that stinking thiols can be replaced by the almost odourless (DODT) without negatively affecting the purity of the end product.
