Protein quantitation assays are essential for workflows that include protein extraction, labeling, and analysis. The simplest method for protein quantitation is measuring the absorbance of a protein ...

IN the course of investigating the dissimilation of biuret by micro-organisms, we found that all of seven strains of Pseudomonas aeruginosa examined were inducible for an enzyme, or enzyme system, ...

Mehl announced in 1945 1 that by the use of ethylene glycol an alkaline copper reagent could be prepared in which copper, besides not being precipitated, could give the biuret reaction. At the high ...

From the decades-old biuret reaction to the use of complicated fluorescent molecules, the search for an easy, reliable, and stable method for the quantitation of total protein in solution has gone on ...
