blue color
Fluorine-containing complexes exist only as 1,2- and 1,10-anthraquinoid structures, which are responsible for their blue color.
      
Colonies produced by this maneuver not only remained sensitive to ampicillin but were also incapable of blue color production on X-gal-containing media, thus demonstrating true blockade of pUC19 replication, rather than antisense activity.
      
This test is based on the ability of the live scale enzymes to react with iodine, yielding iodine products which in turn are unable to give the blue color reaction with starch.
      
Acetaldehyde reacts with sodium nitroprusside producing a blue color.
      
The primary red-green-blue color coordinate system is first transformed into the saturation-hue-brightness color coordinate system.
      
Alkaline solutions of nicotinamidoxime containing traces of nickel(II) give a deep blue color on treatment with iodine.
      
The highly sensitive method is based on the observation of the blue color produced as the result of ion association of phosphomolybdate and malachite green in acidic medium.
      
Iron (III) and tin(II) ions caused considerable discoloration and precipitation: the strong blue color in berry juices was due to tin (II) complexes with cyanidin and delphinidin glycosides, whereas iron (III) proved more harmful to red beet juices.
      
Despite its lower stability towards heat and light, phycocyanin was concluded to be the more versatile blue food colorant among the three studied, showing a bright blue color in jelly gum and coated soft candy.
      
The magnitude of these responses was sensitive to both color and frequency parameters; red-blue color-paired flicker consistently produced the strongest constrictions.
      
No evident differences between softwood and hardwood were found in the variation of blue color of all the specimens.
      
The O- center has the same thermal stability as the absorption band centered at 620?nm, which is responsible for the blue color.
      
Fe3+ is not responsible for the blue color because colorless and blue euclase show nearly the same Fe3+ concentration as measured by EPR.
      
However, total iron content in blue sample is much higher than in the colorless one suggesting that the existing model that Fe2+-Fe3+ intervalence charge transfer transition may explain the blue color of euclase.
      
It is confirmed that the absorption due to the O- center is responsible for the blue color in topaz.
      
After addition of tetramethylbenzidine substrate solution, a deep blue color developed, signifying the presence of Hb S or Hb C.
      
The electroluminescence spectrum becomes simplified to have an emission peak at 460?nm for fine blue color when the copolymer is blended with poly(vinylcarbazole) with a ratio of 1 to 4 before the use as an emissive layer.
      
In addition, a method was designed to visually identify homogeneous transformed colonies, derived from zoospores of transformed multinucleated Phytophthora mycelia, based on blue color development on plates containing X-Gluc.
      
The selected plantlets exhibited strong GUS activity in leaves and roots as indicated by a deep blue color.
      
Both the experimental and theoretical results show that inserting a hole blocking layer between two adjacent emission layers will make the color tunable region move toward the wide bandgap emission layer of blue color in our case.
