Determination of cellular aminopropyltransferase activity using precolumn fluorescent etheno-derivatization with high-performance liquid chromatography.
Polyamines such as spermidine (Spd) and spermine (Spm), produced by aminopropyltransferase (Apt), play roles in cell growth and differentiation. A sensitive and simple fluorometric high-performance liquid chromatographic determination for Apt activity of spermidine synthase (Spdsyn) and spermine synthase (Spmsyn) was developed in order to examine cellular functions of polyamine synthesis. The d...
متن کاملDetermination of boronophenylalanine in biological samples using precolumn o-phthalaldehyde derivatization and reversed-phase high-performance liquid chromatography.
A reversed-phase high-performance liquid chromatographic method for the detection of boronophenylalanine is described. Determination was obtained by precolumn reaction of o-phthalaldehyde with a mixture of standard amino acids containing boronophenylalanine and separating the corresponding o-phthalaldehyde derivatives, using a Kromasil C-18, 250 x 4.6 mm, 5-microm particle size column, a step g...
متن کاملHigh-Performance Liquid Chromatography Determination of Methotrexate in Plasma
This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...
