Abstract A new method for determinating diaminopimelic acid (DAPA) from rumen fluid was developed. The concentration of DAPA is used as an indicator for the estimation of protein content of bacterial… (More)
Abstract Mercaptoethanesulphonic acid (MES-OH) (3 M) was used for the hydrolysis of different samples (pure proteins, free typtophan and milk powder with a high sugar content). Different temperatures… (More)
SummaryA screening method using nonaqueous capillary electrophoresis (NACE) has been developed for purity analysis of pyridinyl-methyl-sulfinyl-benzimidazoles (PMSB). Eight different polar organic… (More)
Photophysical and photochemical properties of o-phthalaldehyde/s-mercaptoethanol-labelled aliphatic α-peptides were investigated. It is found that α-peptide derivatives have lower fluorescence… (More)

Abstract A method for the evaluation of the age of wool carpets and textiles was developed based on the age dependent alteration of amino acid composition of proteins. Samples of 23 wool carpets and… (More)
Micellar electrokinetic chromatography (MEKC) was examined for the separation of labelled d- and l-amino acids to permit rapid screening of protein amino acid enantiomers in microchemical analytical… (More)
