Specific labeling of tyrosine residues of Streptomyces subtilisin inhibitor (SSI) was carried out by dansyl chloride. Analysis revealed that two tyrosine residues out of three in SSI were modified. The resulting fluorescent SSI was fully active as a subtilisin inhibitor.

A database search using peptide mass fingerprints obtained by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry leads to protein identification with incomplete sequence coverage, because certain peptides are preferentially desorbed/ionized and some are not detected at all. We show that certain

Detection of human parotid salivary proteins by dansylation and UV-transillumination after sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) has been compared with Coomassie Blue R-250 and silver staining procedures. Dansylation gives superior results in terms of both resolution and sensitivity, especially
