J. Chromatogr. B 737 (1/2), 71-77 (2000). Description of a fast and effective three-step purification procedure for a fragment of FKBP52, consisting of affinity chromatography, anion-exchange and gel-permeation chromatography. Verification of the purity of the products by SDS-PAGE.

CBS 110, 10-11 (2013). New HPTLC silica gel plates specially suited for coupling with MS and TLC plates for coupling with NMR. These MS-grade HPTLC plates are low in impurities and show less background noise, the layer thickness is 100 µm. HPTLC of human insulin and its secondary components on MS-grade silica gel with 2-butanol - pyridine - ammonia 25 % - water 39:34:10:26, detection under UV 366 nm after treatment with fluorescamine and by elution with the TLC-MS Interface and Q-TOF MS analysis in ESI positive mode, the eluent was acetonitrile - water 19:1. Separation and identification of insulin and desamido insulin was achieved, even though there is only 1 Da mass difference.

Anal. Biochem. 206, 168-171 (1992). Description of a rapid immunochromatographic method for the analysis of protein antigents, based on „sandwich“ assay format using monoclonal antibodies of two distinct specificities, one covalently immobilized to a defined detection zone on a porous membrane while other serve as a label. The sample is mixed with the coating, and the mixture is then passed along a porous membrane by capillary action past the antibodies in the detection zone, giving a blue color. Detection limit, below the nanomolar range for the antigen, human chlorionic gonadotropin.

J. Chromatogr. 698, 89-105 (1995). A review with 54 references on the basic principles of affinity electrophoresis and quantitative affinity electrophoresis with the latest applications, especially the thermodynamic analysis of biospecific interactions by affinity electrophoresis and the development of two-dimensional affinity heterogeneity, lectin affinity electrophoresis for characterizing glycoprotein and newly developed capillary gel affinity electrophoresis.

J. Chromatogr. B 737 (1/2), 63-69 (2000). The title protein was expressed in Escherichia coli forming insoluble inclusion bodies (Ibs) and purified in a three-step, hydrophobic interaction and gel permeation chromatography. Determination of the purity of the CH2 protein by a silver-stained SDS-PAGE.

CBS 108, 4-5 (2012). HPTLC of human insulin recombinant and porcine and bovine pancreas insulin on ProteoChrom silica gel with 2-butanol - pyridine - 25 % ammonia - water 39:34:10:26 to 50 mm migration distance. Detection under UV 366 nm after spraying with 0.02 % fluorescamine in acetone. Elution with the TLC-MS Interface and MS analysis in ESI positive mode, the eluent was acetonitrile - water 1:1. The hRf value of human, porcine and bovine insulin was 50. All mass spectra could be clearly assigned to the different insulin samples.
