A possibility of using tryptamine as a reactive matrix for the analysis of non-polar carbonyl compounds by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry has been shown. Presence of a terminal primary amine group in the tryptam

The derivatization reagent was prepared in situ by the reaction of tris(2,6-dimethoxyphenyl)methylium hexafluorophosphate with N-(2-aminoethyl)maleimide and used for the modification of a number of low molecular weight thiols. The adducts were analyz

A novel derivatization method for the analysis of primary amines by MALDI mass spectrometry is proposed. Tris(2,6-dimethoxyphenyl) methyl carbenium cation reacts smoothly with primary amines, forming permanently charged adducts with the mass incremen

A concentrate with the antimicrobial activity has been isolated from the culture broth of Streptomyces roseoflavus INA-Ac-5812. Its further fractionation by reversed-phase HPLC has resulted in six fractions. It has been established by MALDI-TOF and E

Some aromatic carbonyl compounds [2,4-dihydroxybenzaldehyde (2,4-DHBA), 2,5-dihydroxyacetophenone (DHAP), 2,3,5-trihydroxybenzaldehyde and 2,4-dinitrobenzaldehyde] were examined as potential reactive matrices for the analysis of mono-, di-, and polya
