A simple and efficient colorimetric method for the naked-eye detection and quantification of histidine in biological fluids was developed based on an indicator-displacement assay (IDA) and the Ni(2+)-histidine affinity pair. In this IDA approach, a commercially available dye, murexide, was used as the indicator and the selective detection of histidine was achieved based on the competition betwe...

Abstract A biodegradable thermoplastic polymer has been formulated by solubilizing Murexide (M) salts in a commercial vinyl alcohol copolymer (HVA). The employed as self-healing filler with the aim to impart auto-repair ability material. Three different percentages (1, 3, and 5 mass%) of have solubilized HVA evaluate effect concentration on thermal properties resulting polymeric materials. samp...

The chromometallic dye murexide was used to measure photoreversible Ca fluxes in apical tips of etiolated oat coleoptiles and in suspension cultures of protoplasts derived from the coleoptile segments. Phytochrome presence in the protoplasts was indicated by a repeatably photoreversible DeltaA(725 - 800 nm) of >0.001 A centimeters(-1), recorded on a dual wavelength spectrophotometer. Concentrat...

the objective of this study was to assess the adsorption potential of activated carbon (ac) asan adsorbent for the removal of murexide (mu) from aqueous solutions. the influence of variablesparameters including ph, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon mu removal was studied. following optimization of variables, the relation between concentrations ofdye re...
