Cumulative CAMAG Bibliography Service CCBS
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.
J. Liq. Chromatogr. Relat. Technol. 31, 752-762 (2008). TLC and HPTLC of nine dipeptides (gly-gly, ala-gly, pro-leu, pro-asp, pro-gly, leu-pro, ala-pro, phe-pro, val-pro) on silica gel with ethanol - dichloromethane 2:1 and methanol - dichloromethane 1:1 in a horizontal chamber saturated for 20 min. Detection by spraying with sodium azide and starch solution (25 mL aqueous starch solution, containing 2.5 g starch, was added to 20 mL aqueous sodium azide solution containing 2 g sodium azide, the mixture was adjusted to pH 5.5 with 0.1 mol/L hydrochloric acid and diluted to 50 mL with water to obtain 4 % and 5 % solution for sodium azide and starch, respectively). All solutions were prepared fresh daily. The limit of detection was 2-200 pmol/spot for the iodine azide procedure, 1-100 pmol/spot for iodine, 20-2000 pmol/spot for UV 254 nm, and 40-1000 pmol/spot for spraying with ninhydrine and drying at 110 °C .
Anal. Chem. 324, 339-340 (1986). TLC of dipeptides on a) microcrystalline cellulose with pyridine - water 2:1 and 4:1 and b) on chiral plate with methanol - water - acetonitrile 5:5:20 and 5:5:3. Detection with ninhydrin reagent.
J. Chromatogr. 448, 11-30 (1988). TLC of proteinogenic and non-proteinogenic amino acids, dipeptides and a-hydroxy acids. Separation of the enantiomers, without derivatization, on a chiralplate. Quantification by densitometry. Determination of the respective enantiomers at trace levels (0,25%). Detection limits: 0.1% of the minor enantiomer. Other examples from the field of +-methyl, N-alkyl and halogenated amino acids.

Anal. Chem. 79, 486-493 (2007). TLC of methylene blue and methyl red on monolithic phase with ethyl acetate - ethanol -water 6:4:3 and 3:2:1 with chamber saturation for 30 min. After development the plates were dried and scanned with MALDI. TLC separation of fluorescamine labeled proteins (insulin, cytochrome c, lysozyme, and myoglobin) with 40 or 55 % aqueous acetonitrile and 0.1 % trifluoro acetic acid with chamber saturation for 30 min.
