Fast Black K Salt: a visualization reagent for thin-layer chromatography of beta-adrenergic blocking drugs
J Anal Toxicol 1988 Mar-Apr;12(2):108-10.PMID:2898037DOI:10.1093/jat/12.2.108.
A sensitive visual method for the thin-layer chromatography of beta-adrenergic blocking drugs is described. The Rf values and the detection limits of eleven beta-blockers extracted from urine and as pure drugs are given. Other commonly used cardiovascular drugs are shown not to interfere with the method. The procedure is applicable to both urine and liver extracts.
Facile detection of anatoxin-a in algal material by thin-layer chromatography with Fast Black K Salt
Analyst 1991 Mar;116(3):265-7.PMID:1906687DOI:10.1039/an9911600265.
A method for facile high-capacity screening of algal samples for anatoxin-a (ANTX-a), a potent neurotoxin of Anabaena flos-aquae, is presented. The method is based on in situ colour reaction of algal extracts containing ANTX-a on a thin-layer chromatographic plate with the diazonium reagent Fast Black K Salt, and subsequent separation of the orange-red product. The product, shown to be a stable 3,3-dialkyltriazene, is derived from a reaction involving the aliphatic secondary amino group of ANTX-a. The detection limit for ANTX-a is 10 micrograms g-1 of lyophilized algal material, which is comparable to earlier methods using more complex instrumentation.
Development of a diagnostic test for anaerobic periodontal infections based on plaque hydrolysis of benzoyl-DL-arginine-naphthylamide
J Clin Microbiol 1990 Jul;28(7):1551-9.PMID:2380379DOI:10.1128/jcm.28.7.1551-1559.1990.
Treponema denticola, Porphyromonas (Bacteroides) gingivalis, and Bacteroides forsythus are among the anaerobic species frequently associated with adult forms of periodontal disease. These organisms hydrolyze the synthetic peptide benzoyl-DL-arginine-naphthylamide (BANA), and such enzyme activity can be detected in the plaque and related to clinical disease and the presence of spirochetes. In this investigation, the liquid BANA assay was compared with a commercially developed BANA assay which employed a paper format and which could be read after a 15-min incubation. In the paper format, strips of a Whatman filter paper were impregnated with BANA and strips of nitrocellulose paper were impregnated with Fast Black K Salt. Both strips were applied lengthwise across a paper card (3 by 5 in. [7.6 by 12.7 cm]). The BANA strip at the bottom was inoculated with the test sample (pure culture, plaque), folded back so that it contacted the fast black strip, and then incubated for 15 min at 55 degrees C. T. denticola, P. gingivalis, and B. forsythus always gave a positive reaction, whereas 51 other plaque species were always negative. Six Bacteroides and Capnocytophaga species on occasion had weak reactions. The proportional agreement between BANA positiveness and clinical disease was similar for both the liquid and the paper assays. The sensitivity, specificity, and accuracy relative to the clinical standard of the liquid assay were 74, 76, and 77%, respectively, while those of the paper assay were 81, 78, and 80%, respectively. The paper assay was significantly associated with the presence of either T. denticola or P. gingivalis or both in the plaque samples, with a sensitivity of 85%, a specificity of 53%, and an accuracy of 79%. These findings indicate that a rapid paper assay for BANA hydrolysis gives data comparable to those obtained with the liquid BANA assay.
[Thin-layer chromatography analysis of methamphetamine in urine samples]
Ceska Slov Farm 1996 Nov;45(6):279-83.PMID:8998609doi
The paper investigated the chromatographic conditions for TLC analysis of metamphetamine on silica gel and the lipophilic stationary phase RP V 18 in order to qualitatively analyze the drug in urine samples. Attention was also paid to chemical detection. Five detection reagents were tested, out of which Fast Black K Salt, yielding orange-red spots with a detection limit of 1 microgram, proved to be the best. In the analysis of metamphetamine in the samples of model urine, the best results were achieved on Kieselgel. Using the developing system ethyl acetate-ethanol-concentrated solution of ammonia (36:2:2), a complete separation of the metamphetamine spot from the spots of ballast from the biological matrix was achieved.
