These are composite structures of chitinous cuticle and resilin, which was identified by its brilliant pH-dependent fluorescence and its limited spectral signature [ 18, 28].
To create the sensor itself, brilliant yellow (BY) as a pH indicator and poly allylamine hydrochloride) [PAH] as a cross-linker have been deposited on the end of a bare silica core of an optical fibre by use of a 'layer-by-layer' technique.
The catalytic properties of the as-grown solar photocatalyst were studied by degrading acridine orange (AO) and brilliant cresyl blue (BCB) at different pH under solar light.
Further, we evaluated the photocatalytic performance of ΝΜ at different pH under solar light, using brilliant cresyl blue (BCB) as organic pollutant.
To test this assumption, in a typical experiment, 100 mg of hollow Na0.15WO3 nanospheres was suspended in 2 mL, 60 μg/mL of Coomassie Brilliant blue (a common dye) aqueous solution with pH = 2.
For isoelectrofocusing, samples were diluted with rehydration buffer containing 8.3 M urea, 1 M thiourea, 2% (w/v) CHAPS, 0.28% (v/v) dithiothreitol, 2% (v/v) IPG buffer (pH 3 10), and 0.01% (w/v) Coomassie Brilliant blue R-250.
The supernatant equal to 10 mg Chl was mixed with one-tenth volume of 1 % Coomassie brilliant blue G-250 in 100 mM BisTris-HCl (pH 7.0), 0.5 M 6-amino-n-caproic acid, and 30%% glycerol.
A sample of 20 μL of the resulting supernatant was collected and added to 80 μL of 0.04 mol/l phosphate buffer (pH = 7. 0) and 200 μL of Coomassie brilliant blue (Shanghai Kayon Biological Technology Co., Ltd).
The gels were then incubated overnight at 37°C with 0.1% glycine buffer pH 7.5 and then stained with 0.5% Coomassie Brilliant Blue R250 and destained.
In initial screening study, the maximum decolorization (84.8%) of Solar brilliant red 80 was achieved in 7 days shaking incubation period at pH 4.5 and 30 °C.
Samples were diluted (1 2) with a sample buffer (100 M Tris-HCl, pH 6.8, 1% SDS, 4% 2-mercaptoethanol, 0.02% brilliant blue G, and 24% glycerol) (S3047, Sigma) and heated at 100 °C for 4 min.
