J. Planar Chromatogr. 5, 267-270 (1992). Determination of the lipophilicity of 17 non-ionic tensides (nonphenyl and tributylphenyl ethylene oxide oligomers) by RPTLC with methanol , ethanol , and 1-propanol as organic modifiers of the aqueous mobile phase. Rm values decreased linearly with increasing concentrations of organic modifier. TLC on silica impregnated by overnight predevelopment with hexane - paraffin oil 95:5, and aqueous methanol, ethanol and 1-propanol (various alcohol concentrations). Detection with modified Burger reagent (G.F. Longman, The Analysis of Detergents and Detergent Products, Wiley and Sons, London, (1977), 517).

Discussion of the differences between different tissues, which would aid in the diagnosis of thyroid malignancy, and for differential diagnosis of follicular neoplasm.

Anal. Biochem. 239, 123-129 (1996). Two-dimensional electrophoresis on polyacrylamide gel (PAG) with 0.025 M Tris-0.195 M glycine buffer (pH 8.6) at a constant 30 mA electric current. Fixation with 1% acetic acid, and staining with o-dianisidine solution. Discussion of Hb binding with some of the smaller individual polymeric molecules of Hp subtypes and variants. Detection also of the capacity for combining with hemoglobin of each polymer of the variants.

J. Chromatogr. B 823 (2), 152-157 (2005). HPTLC of lamotrigine (extracted from serum by ethyl acetate) on silica with toluene - acetone - ammonia 14:6:1. Densitometric measurement at 312 nm, hRf of lamotrigine at 54. The analytical method has excellent linearity (r = 0.998) in the range of 20–300 ng/spot. This assay range is adequate for analyzing human serum, as it corresponds to lamotrigine concentrations measured in human serum from epileptic patients. The method was validated for sensitivity, selectivity, extraction efficiency, accuracy and intra and inter-day reproducibility. The limit of detection and limit of quantification were found to be 6.4 and 10.2 ng, respectively. Good accuracy and high precision (CV) is reported, i.e. in the range of 92.1-97.1 % and 0.5-2.6 % respectively. The method was applied for determination of serum lamotrigine levels in epileptic patients and in pharmacokinetic study of lamotrigine administered orally to rabbits.

CBS 101, 2-4 (2008). HPTLC of amino acids (from hydrolysis of peptides) on silica gel, Diol phase, and cellulose with either 2-butanol - acetic acid - pyridine - water 15:3:10:12 or 2-butanol - 25 % ammonia - pyridine - water 39:10:34:26 in a twin-trough chamber or horizontal chamber. Detection by dipping in ninhydrin solution (0.5 % in 2-propanol) followed by heating at 110 °C for 5 min. Better results are achieved by adding ninhydrin directly to the mobile phase at a 0.5 %-level. Quantitative determination by absorbance measurement at 440 nm. Selectivity was better on the cellulose and silica gel plate. Selection of the chromatographic system depended on which amino acids had to be separated and no general recommendation could be given. HPTLC analysis of a hydrolyzed peptide sample (containing Phe, Trp, D-Bal, Apc and Inp) on cellulose with the acidic mobile phase. All five amino acids were quantified between 70 and 130 % of the theoretical value for non-stable amino acids (degradation 5 to 30 %).
