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:
- Full text search: Enter a keyword, e.g. an author's name, a substance, a technique, a reagent or a term and see all related publications
- 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. Planar Chromatogr. 19, 252-254 (2006). TLC of 22 amino acids on silica gel with n-propanol - water 7:3. Detection by spraying with 0.25 % 2,3-dichloro-1,4-naphthoquinone in ethanol, followed by drying in the air at room temperature and heating in an oven at 110 °C for 10 min. After cooling spraying with 0.4 % isatin in ethanol. Visual detection of spot colors (varying from yellow, to orange, pink, purple, and gray). Detection limits were determined visually and ranged from 0.01 µg (cystine and arginine) to 0.30 µg (isoleucine, phenylalanine, methionine, aspartic acid, and glycine).
J. Chromatogr. A 1440, 240-248 (2016). Our previous report showed that RP-18 phases for HPTLC provide complex retention mechanisms based on various polar and nonpolar interactions. Here we show that for the chromatography of peptides, due to mixed-mode properties of these adsorbents, there is a simple way to obtain inversion of a separation system (from reversed-phase to normal-phase, and vice versa). The system inversion leads to a significant change of selectivity, which may be useful in 2D separation of complex samples of basic/amphoteric compounds such as peptides. This results from the fact, that RP-18 phases for HPTLC may be used in hydrophilic interaction chromatography (HILIC) or RP chromatography, depending on the mobile phase composition.
Detection under UV at 365 nm. Quantification by fluorometry following elution with methanol.
J. of Medicinal Chemistry 31, 671-677 (1988). TLC of N-t-BOC group, BOC-Sta-Ile-Phe-OCH3 and BOC-His(Tos)-Sta-Ile-Phe-OCH3 on silica with 4% methanol - 96% dichloromethane, 4% methanol - 96% dichloromethane - NH4OH saturated, 8% methanol - 92% dichloromethane, 8% methanol - 92% dichloromethane - NH4OH saturated.
2. Polar tri- and tetrapeptides. J. of Medicinal Chemistry 32, 1108-1118 (1989). TLC of tri- and tetrapeptides on silica various mixtures. Visualization under UV and/or by spraying with ninhydrin, t-BuOCl/starch KI or Sakaguchi reagent.
I. Acta Chimica 129, 871-877 (1992). TLC of thyrotropin hormone on silica with chloroform - methanol 9:1 or ethyl acetate - stock 6:4 (stock solution = pyridine - acetone - water 20:5:11).
J. Liq. Chrom. & Rel. Technol. 24, 1511-1514 (2001). TLC of a peptidoglycan monomer (PGM) (GlcNAc-MurNAc-L-Ala-D-isoglutaminyl-meso-diamino-pimelyl-D-Ala-D-Ala), some metals and their complexes on cellulose with n-propanol - NH3 - water 7:3:1 and n-butanol - ethyl acetate - acetic acid - water 1:1:1:1. Detection of the metal complexes by e.g. dipping the plate in a 0.25% solution of (1-(2-pyridylazo-2-naphthol)) in ethanol. Detection of PGM by dipping in 0.2% ethanolic ninhydrin solution and heating at 110°C.
J. Chromatogr. 233, 355-360 (1982). TLC on silica with chloroform - methanol -ethyl acetate - acetone - triethylamine 70:15:10:10:5. Detection by fluorometry at 240 nm.
