Biochem. Biophys. Res. Commun. 372, 480-485 (2008). 2D-TLC of alpha-32P ATP or alpha-32P UTP labeled nucleotides after RNase T2 treatment of tRNA transcripts synthesized by T7 RNA polymerase, on silica gel with isobutyric acid – ammonia – water – 66:1:33 for the first dimension and isopropyl alcohol – hydrocloric acid – water 14:3:3 for the second dimension. Quantitative determination by radioactivity measurement of the labeled nucleotides.

Pharm. Res. 33, 1587-1601 (2016). HPTLC study of the cleavability of the disulfide bond in a conjugate siRNA-S-S-PE (incubated in 10 mM glutathione at 37 °C for 4 h) on silica gel with chloroform – methanol 4:1. Detection by spraying with molybdenum blue dye for the cleaved phospholipids. This test confirmed the potential utility of this system for siRNA delivery in vivo.

J. Planar Chromatogr. 2, 194-197 (1989). Discussion of a new method for preparing surface-enhanced Raman spectroscopy using silver colloidal spheres deposited on HPTLC plates. The sensitivity permits the aquisitation of Raman spectra from HPTLC spots down to 1 µm in size. It is possible to identify organic substances in the pico- and femtogram region of mass.

J. Chromatogr. 574, 41-55 (1992). Two-dimensional TLC of DNA adducts, labeled by shot-gun 5'-phosphorylation of representative 32P-a-deoxyribonucleotide monophosphates, on PEI cellulose with 0.1 M acetic acid (pH 3.5) for the first dimension and 5.6 M (NH4)2SO4, 0.12M Na2EDTA, and 0.035M (NH4)HSO4 (to pH 4) for the second at temperature of 17°C, 50-60% humidity constant. The technique quantifies low-molecular - mass adducts and DNA integrity both in vivo and in vitro.

J. Chromatogr. 580, 293-323 (1992). Discussion of 32p-postlabelling technique as a human carcinogen - DNA adduct biomonitoring method, involving enzymatic preparation and labelling of DNA samples, followed by TLC and HPLC separation of carcinogen - nucleotide adducts from unadducted nucleotides. Use of both synchronous fluorescence and HPLC in conjunction with 32p-postlabelling and TLC to confirm the identity of specific carcinogen DNA adducts in human samples.

J. Chromatogr. 612, 295-301 (1993). TLC of 32P-postlabeled DNA adducts on polyethyleneimine-cellulose with different mobile phases. Detection by intensifying screen-enhanced autoradiography. Quantification by Cerenkov counting with adducts expressed in counts per minute. Discussion of the separation, resolution, recovery, retention of background noise, and developing time.

J. Chromatogr. 614, 245-251 (1993). Investigation of the suitability of RP-18 TLC for enhancement of adducts in the 32P-postlabeling assay, for structurally diverse classes of DNA adducts derived from benzo[a] pyrene, 2-acetylaminofluorene, benzoquinone, sarfrole, and mitomycin C. Retention of adducts to C18 phase followed by elution with organic solvent - water. Comparison of adduct recoveries with those obtained by nuclease P1 and butanol methods.

J. Chromatogr. 645, 189-192 (1993). HPTLC of DNA 5-methylcytosine on alkyl amino modified silica with isobutyric acid - water - NH3 177:8:3. Detection under UV 254 nm. Quantification by scintillation counting. Comparison with traditional two-dimensional procedure on polyethyleneimine cellulose and HPLC method.
