Tailored correlation spectroscopy for the enhancement of fingerprint cross peaks in peptides and proteins

J Quant et al. J Magn Reson B. 1995 Feb.

Abstract

A new experimental mixing scheme for band-selective Hartmann-Hahn transfer between the HN and H alpha resonances of peptides and proteins is presented. This form of tailored correlation spectroscopy (TACSY) allows enhancement of the sensitivity of specific (HN-H alpha)-fingerprint signals compared to broadband TOCSY experiments. The design criteria as well as experimental applications of the multiple-pulse sequence CABBY-1 are presented.
