J. Planar Chromatogr. 26, 455-456 (2013). HPTLC of oligopeptides on RP-18 (chromatography described in R. Gwarda, A. Tomczyszyn, A. Misicka, T.H. Dzido, Acta Chromatogr., in print, 2015). Detection by spraying or dipping for 2 s with 2 % ninhydrin solution in 1) acetone - glacial acetic acid 25:1 or 2) acetone - methanol - glacial acetic acid 25:25:2, followed by heating at 80 ºC. Results showed that short dipping of the plate in ninhydrin solution resulted in a better detectability of peptides than spraying it with the same solution. Solution 2) with methanol made the ninhydrin reaction faster, and colored all zones in a distinct pink/red color, unfortunately one peptide (no. 1) showed poor color intensity.

J. of Chromatogr. A 1281, 135-141 (2013). The use of detergents for the extraction, solubilization and purification of membrane proteins (MPs) is necessary due to their hydrophobic nature. Detergent quantification is essential to routine analysis because the concentration of amphiphiles is crucial in the crystallization process. HPTLC of detergents (in small quantities, bound to solubilized MPs) on silica gel with dichloromethane – methanol – acetic acid 80:19:1. The optimum HPTLC conditions were investigated using n-dodecyl-beta-D-maltoside (DDM), the most popular detergent for membrane protein crystallization. Quantification by fluorescence measurement at 366 nm using a Hg lamp. The calibration curve was linear in the range of 100-1600 ng of DDM in water and the limit of detection of was 50 ng/zone, which is the best LOD achieved to date for a routine detergent assay (not modified by the addition of NaCl, commonly used in protein buffers). In comparison with other techniques (colorimetry, GC, and FTIR) the HPTLC method has the advantage of no prior sample treatment for concentration or extraction, and no chemical labeling is required. In comparison with TLC, the HPTLC method is 100 times more sensitive. The HPTLC method is suitable for routine analysis, assay results are obtained within 3 hours and only few microliters of sample are needed.
