Chromatogr. Sci. 55, 249-281 (1991). A review with 87 references on theoretical foundations of quantitative analysis in TLC by optical means as well as in electrophoretic separations on optically similar media.

J. Chromatogr. 698, 251-261 (1995). A review with 84 references on non-denaturing gel electrophoresis of biological nanoparticles, emphasizing on the characterization of particles and gels, the application to both viruses and solid virus-related particles, or to both viral DNA and DNA-protein complexes. Discussion also of the biomedical perspective.

J. Chromatogr. A 731, 139-151 (1996). SDS-PAGE of proteins collected from the immobilized artificial membrane column. Detection by scanning densitometry at 400 nm for the silver-stained 15 % polyacrylamide gel. Measurement of the protein contents by using bicinchoninic (BCA) protein assay kit. Qualitative assay of phospholipase Az by color reaction, and quantification with radioactive method. Discussion of the use of IAMs to develop purification methods for the enzymes obtained from diverse biological specimens.

Planar Chromatogr. 10, 332-335 (1997). The use of electroosmotically driven separations remains a neglected area in modern planar chromatography. Here the arguments for the re-investigation of thin-layer electrophoresis (TLE) or planar electrochromatography (PEC) are considered. The methods appear to offer a number of advantages compared with conventional techniques, and although technical problems remain to be overcome the work already published suggests that further investigation of this area with modern HPTLC layers would prove very fruitful.

Chromatographia 31, 281-284 (1991). TLC of metal ions on synthesized carbamide - formaldehyde polymer or on cellulose with 11 neutral and acidic eluents. Detection by spraying with saturated aqueous solution of (NH4)2S, solution of dithizone (0.1%) in chloroform, and solution of 8-hydroxyquinoline (0.5%) in 60% aqueous ethanol and exposing to NH3 and under UV 254 nm. Comparison of both layers.

J. Chromatogr. 698, 361-367 (1995). Two-dimensional gel electrophoresis of proteins. Discussion of the approach in providing data on protein synthesis in different stages of limb regeneration or comparative data with other regenerative processes such tail and lens regeneration. Comparison with other methods employing gene cloning or generation of antibodies.

J. Chromatogr. A 731, 293-298 (1996). Presentation of a staining techniques for glucose oxidase activity on polyacrylamide gels, based on the fact that glucose oxidase reacts with one-electron scavengers in a reaction dependent on pH and pO2. Demonstration of reduction of ferricyanide, cuprisulfate, ferrycytochrome C and nitrotetrazolium blue reduction leading to sharp colored bands under aerobic conditions. Comparison with conventional peroxidase/O-dianisidine-assay.

J. Planar Chromatogr. 11, 244-246 (1998). Separation of a mixture of dyes by planar chromatography using electroosmotic flow. Separation is faster and peak shape is better than that obtained by conventional planar chromatography. When using a potential of 3.0 kV a mobile phase flow of 2 cm/min was observed during the early part of the development, but this diminishes as the separation proceeds. TLC of a dye mixture on RP-18 with water - ethanol 1:4 containing 1 mM TAPS buffer as mobile phase.
