title: Profiling cells and body fluids--chromatography and two-dimensional electrophoresis as complementary techniques.
abstract: Recent results on the use of gas chromatography-mass spectrometry, high-performance liquid chromatography with diode array detector, amino acid analysis and high-resolution two-dimensional (2-D) electrophoresis to study body fluids and cells in health and disease are surveyed. The chromatography profiling techniques are particularly suitable for the diagnosis of inborn errors of metabolism, with DNA technology as a complementary tool for prenatal diagnosis. Both chromatography and electrophoresis were utilized to study pre-diagnostic sera from the JANUS serum bank and to classify certain bacteria. Protein profiling by 2-D electrophoresis was employed to identify marker proteins associated with the metastatic properties of cloned cancer cells. The electrophoretic technique is also appropriate as a preparative tool for isolating sufficient amounts of marker proteins for microsequencing of amino acids. Chromatography and protein profiling were complementary tools for evaluating the toxicity and mutagenicity of environmental samples in a new test utilizing living human leukocytes and fibroblasts.
