General description
α-Cyano-4-hydroxycinnamic acid is the commonly used matrix for analyzing peptides by matrix-assisted laser desorption/ionization mass spectrometry. It inhibits the monophenolase activity and diphenolase activity of mushroom tyrosinase.
Application
α-Cyano-4-hydroxycinnamic acid(CHC) was used as a matrix for peptides and nucleotides in mass spectroscopic analysis. It was used in encapsulation of CHC into NaY zeolite. It was used as matrix to investigate the activity of the paclitaxel derivatives using several well-established in vitro angiogenesis assays.

A commercially available, matrix-assisted, laser desorption/ionization (MALDI), time-of-flight mass spectrometer has been used for the successful characterization of picomole quantities of modified deoxyoligonucleotides. The procedure was found to be applicable to the analysis of a variety of modified synthetic structures

During the analysis of an Asp-N digest of a recombinant hematopoietic growth factor by matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS), we observed pseudomolecular ions corresponding to reduced forms of peptides known to be present only in single disulfide linkages.

We describe here an optimization study of the sample preparation conditions for sensitive detection of peptides by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Among many factors in the conditions, we varied the percent acetonitrile in the peptide solution, the percent
