Our CCBS database includes more than 11,000 abstracts of publications. Perform your own detailed search of TLC/HPTLC literature and find relevant information.
The Cumulative CAMAG Bibliography Service CCBS contains all abstracts of CBS issues beginning with CBS 51. The database is updated after the publication of every other CBS edition. Currently the Cumulative CAMAG Bibliography Service includes more than 11'000 abstracts of publications between 1983 and today. With the online version you can perform your own detailed TLC/HPTLC literature search:

- Browse and search by CBS classification: Select one of the 38 CBS classification categories where you want to search by a keyword
- Keyword register: select an initial character and browse associated keywords
- Search by CBS edition: Select a CBS edition and find all related publications
Registered users can create a tailor made PDF of selected articles throughout CCBS search – simply use the cart icon on the right hand of each abstract to create your individual selection of abstracts. You can export your saved items to PDF by clicking the download icon.
The Weizmann Institute of Science, Rehovot, Israel. Reversed phase TLC of dansyl amino acids on silica pre-treated with a copper-II-complex of N, N-di-n-propyl-L-alanine, with buffer A (0.3 M sodium acetate in 40 % acetonitrile and 60 % water adjusted to pH 7 by acetic acid). Detection by UV 360 nm.
J. Liquid Chrom. 10, 3647-3652 (1987). TLC of 15 amino acids on silica and on silica impregnated with 0.1M solutions of hydroxides of Mg, Ca, Sr and Ba with n-butanol - formic acid - ethanol 3:1:1. Detection with 0.2 % ninhydrin in acetone and heating at 70 °C for 10 min.
J. Planar Chromatogr. 7, 54-57 (1994). TLC of L-lysine, L-thionine, L-homoserine, vitamin B12, cobalamine on silica with 3 mobile phases (1-propanol - 25% NH3 - 55:45, 2-propanol - acetone - water - 25% NH3 25:25:7:6, 2-propanol - ethyl acetate - 25% NH3 - water 40:40:3:50 and on alumina with 2-methylpropan-1-ol - 2-propanol - water 3:2:2. Detection of amino acids with ninhydrin. Quantification by densitometry (absorbance at 500 nm for ninhydrin - amino acid complexes and 548 nm for cobalamines). Comparison to videodensitometry with a system developed by the authors.
J. Planar Chromatogr. 15, 371-376 (2002). TLC of 24 amino acids (Gly, Hyd, Ala, n-But, Ser, Pro, Val, Thr, Cyst, Leu, Ile, n-Leu, Met, Tyr, b-Phe, Trp, DOPA, Cys, Orn, Lys, His, Arg, Asp, Glu) on untreated and on triaryl phosphate (TAP)-impregnated talc, starch, silica gel and alumina with dimethyl sulfoxide - 1 M HCl 1:1. Detection with a 0.2% solution of ninhydrin in acetone.
J. Planar Chromatogr. 21, 299-304 (2008). HPTLC of 21 amino acids on silica gel impregnated with 5 % Ag ion with borate phosphate buffer pH 2.3. After drying at 50 °C detection by spraying with ninhydrin. With this system separation of alanine, phenylalanine and tryptophane could be achieved, as well as separation of alanine, tyrosine and tryptophan. Separation of these amino acids was neither achieved on conventional silical gel (without Ag impregnation) nor by addtion of buffered 5 % silver nitrate solution (pH 2.3) to the mobile phase.
J. Planar Chromatogr. 26, 31-36 (2013). TLC of a five-component mixture of the amino acids lysine (1), histidine (2), leucine (3), alanine (4) and glutamic acid (4) on silica gel with 1.0% aqueous urea solution pH 7.44. The hRf values of amino acids (1) to (5) were 38, 59, 78, 87 and 98, respectively. LOD for (1), (3) and (4) was 1.5 µg/zone, whereas for (2) and (5) it was 1.2 and 3.0 µg/zone, respectively.
J. Planar Chromatogr. 29, 145-147 (2016). HPTLC of amino acids in seed cotyledons and seed coats from two types of legumes: black-eyed beans (Vigna unguiculata) and red kidney beans (Phaseolus vulgaris) on silica gel with n-butanol – glacial acetic acid – water 12:3:5. Detection by spraying with ninhydrin reagent 0.2 g/100 mL in ethanol, followed by heating at 80-100 °C for 5 min. The hRF values of essential and nonessential amino acids were determined and ranged between 13 and 62.
Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 93, (1984). TLC and OPTLC of L-lysine, formaldehyde on silica with citrate buffer pH 6.1. Detection with ninhydrin and heating at 80 °C for 10 minutes. Densitometry.
