  • A simple dye-binding method for determining serum albumin, which employs the dye. 2-(4'-hydroxybenzeneazo) benzoic acid. (HBABA), is described. Albumin. We describe a new automated dye-binding method for serum albumin determination with bromcresol purple (BCP) that has several advantages over an existing. As an example of dye-binding technique, a methyl orange procedure will be presented in outline. It is a modification of the method proposed by.
    Thus, if the protein does not contain an ideal number of aromatic residues, then the dye will not be able to bind to the protein efficiently.

    In Graph 1, x is concentration and y is absorbance, so one must rearrange the equation to solve for x and enter the absorbance of the measured unknown. These molecules are frequently used for solubilizing and stabilizing proteins. Authors Authors and affiliations M.

    1. Unlike other protein assays, the Bradford protein assay is less susceptible to interference by various chemical compounds such as sodium, potassium or even carbohydrates like sucrose, that may be present in protein samples. An absorptiometric method for determining ammonia in boiler feed-water.

    2. The equation displayed on the chart gives a means for calculating the absorbance and therefore concentration of the unknown samples.
