[1] determinedthe transient pKa changes of a single amino acid side chain in bacteriorhodopsin, a protein important in photosynthesis. Since bromophenol blue carries a slight negative charge at moderate pH, it will migrate in the same direction as DNA or protein in a gel; the rate at which it migrates varies according to gel density and buffer composition, but in a typical 1% agarose gel in a 1X TAE buffer or TBE buffer, bromophenol blue migrates at the same rate as a DNA fragment of about 300 base pairs, in 2% agarose as 150 bp.

Definitions of the acid dissociation constant and pKa are given below the figures, together with the definition of some classes of organic acids. experiment 11 determination of the pka of bromothymol blue in this experiment, spectrophotometry is used to determine the pka of bromothymol blue, monoprotic. Bromophenol blue (BPB) is most commonly used as an agarose gel electrophoresis size marker. As an acid–base indicator, its useful range lies between pH 3.0 and 4.6. Bromophenol blue migrates at approximately the same rate as 300-500bp DNA in agarose gel and at the buffer front in protein polyacrylamide gels. At low pH, the dye absorbs ultraviolet and blue light most strongly and appears yellow in solution. In gel electrophoresis Bromophenol Blue can be used as a color marker and as as a biological stain. Bromophenol Blue is used as a laboratory indicator, changing from yellow below pH 3 to purple at pH 4.6, and as size marker for monitoring the progress of agarose gel and polyacrylamide gel electrophoresis.

Technische Fragen? Interaktiv. It can be prepared by slowly adding excess bromine to a hot solution of phenolsulfonphthalein in glacial acetic acid.[4]. Bromothymol blue is a member of the class of 2,1-benzoxathioles that is 2,1-benzoxathiole 1,1-dioxide in which both of the hydrogens at position 3 have been substituted by 3-bromo-4-hydroxy-5-isopropyl-2-methylphenyl groups. The pH dependence of binding of bromophenol blue and of bromocresol purple, which has a higher pKa than bromophenol blue, indicated that binding was dependent on protonation of a protein residue with a pKa of 2.9. The pKa of bromophenol blue is 4.0(3), indicating that this compound will almost entirely exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
