The complete bleeding in slaughtering animals is closely related to the halalness of meat. This study aims describe completeness blood drains discarded laying hens carcasses sold at traditional markets Banda Aceh City. research samples were nine chicken bought from three markets, i.e., Peunayong, Ule Kareng, and Seutui (three each market). used a cross-sectional method test perfect carcass with...
Malachite green (MG) is a fluorogenic dye that shows fluorescence enhancement upon binding to its engineered cognate protein, a fluorogen activating protein (FAP). Energy transfer donors such as cyanine and rhodamine dyes have been conjugated with MG to modify the spectral properties of the fluorescent complexes, where the donor dyes transfer energy through Förster resonance energy transfer to ...
Detection of triphenylmethane dyes (TDs), especially the widely used malachite green (MG) and crystal violet (CV), plays an important role in safety control of aquatic products. There are two chromatic forms of TDs: oxidized or reduced. Usually, only one form can be detected by reported ELISA antibodies. In this article, molecular shape superimposing and quantum mechanics calculation were emplo...
cDNA of the glx1 gene encoding glyoxal oxidase (GLX) from Phanerochaete chrysosporium was isolated and expressed in Pichia pastoris. The recombinant GLX (rGLX) produces H(2)O(2) over 7.0 nmol/min/mL using methyl glyoxal as a substrate. Use of rGLX as a generator of H(2)O(2) improved the coupled reaction with recombinant manganese peroxidase resulting in decolorization of malachite green up to 1...
We present a co-precipitation approach for the synthesis of smaller-sized CeO 2 nanoparticles enhanced removal malachite green dye from water.
An electrochemiluminescence (ECL) inhibition method combined with molecularly imprinted solid phase extraction (MISPE) was developed for quantitative determination of malachite green (MG) residues in fish. It was found that MG could strongly inhibit the ECL signal of luminol. Under the optimized conditions, the quenched ECL intensity versus the logarithm of the concentration of MG was in good l...
Photochromic crown compounds, such as monomeric and polymeric crown compounds incorporating spirobenzopyran, spironaphthooxazine, spirobenzothiapyran, Malachite Green, and Crystal Violet moieties, were synthesized for applications in the fields of analytical and separation chemistry. The photochromic crown compounds, especially crowned spirobenzopyran derivatives, were applied to metal ion extr...
A method is described for counterstaining tissue for use with the glyoxylic acid reaction for visual detection of biogenic amines. Counterstaining is achieved by addition of the fluorescent dye malachite green to the sucrose-phosphate-glyoxylic acid (SPG) solution used for processing of cryostat sections of unfixed tissues. When bound to tissues, the dye provides red-orange fluorescence of back...
We report angle-resolved second-harmonic generation (SHG) measurements from suspensions of centrosymmetric micron-size polystyrene spheres with surface-adsorbed dye (malachite green). The second-harmonic scattering profiles differ qualitatively from linear light scattering profiles of the same particles. We investigated these radiation patterns using several polarization configurations and part...
Treatment of dyes from wastewater is obligatory in order to avoid water pollution. Batch adsoprtion studies were carried out to evaluate the potentiality of ba-gases. Various parameters such as initial dye concentration, pH as well as temperature of the system were studied. The adsorption was found to fallow first order kinetics and intraparticle difussion is the date controlling step. The adso...
