Christen Thomsen Barfoed. Christen Thomsen Barfoed (16 June 1815 – 30 April 1889) was a Danish chemist credited with the development of a method to detect monosaccharide sugars in a solution, now known as the Barfoed's test. [1] [2] Barfoed is also credited with having introduced systematic chemical analyses in Danish agricultural sciences. [3]
It is done in one step where the Bradford reagent is added to a test tube along with the sample. After mixing well, the mixture almost immediately changes to a blue color. When the dye binds to the proteins through a process that takes about 2 minutes, a change in the absorption maximum of the dye from 465 nm to 595 nm in acidic solutions ...
