research laboratories‚ and in medical diagnostics. The Bradford assay is dependent on the binding of the dye Coomassie Blue G250 to protein (mainly arginine)‚ in which the dye is equal to the protein concentration. When the protein is absent‚ the solution is a red-brown colour and when the protein binds‚ the pKa of the dye moves causing the dye to become blue. The anionic blue form of the dye‚ which binds to the protein‚ has a maximum absorbance of 590 nm whereas the assay reagent solution of red

(tb) The rate at which photosynthesis happens can be measured using a dye (DCPIP)‚a Hill reaction‚ and a spectrophotometer. ( DCPIP ) 2‚6-dichlorophenolindophenol is a compound that is often used as a redox dye. Oxidized DCPIP is blue‚ DCPIPH‚ which is reduced by a single electron‚ is pink‚ and fully reduced DCPIP is colorless. It is often used in measurements of the electron transport chain

What remains constant is the Mataji‚ who according to the Vaghri tribes‚ protects and helps people. Traditionally maroon and black were the colors used‚ with the surface of the material as the third color. The maroon and black colors were natural dyes sourced from alizarin and oxidized metal.

After experimenting from 1915 to 1921 with additive color systems that filmed and projected the two color components simultaneously‚ rather than in rapid alternation (thereby eliminating Kinemacolor’s color flicker and false color fringes around rapidly moving objects)‚ Dr. Herbert Kalmus‚ Dr. Daniel Comstock‚ and mechanic W. Burton Wescott (who left the company in 1921) developed a subtractive color print process for Technicolor. As in their final additive system‚ the camera had only one lens but

The Iodine Test to identify the presence of starch. The Grease Spot Test and the Sudan Dye test to identify the presence of lipids (fatty acids). The Benedict’s Test to identify the presence of reducing sugars. In the biuret test if the test result for protein changes a color of lavender‚ purple or pink‚ the test result for protein is positive
