WebThe bicinchoninic acid (BCA) assay, first described by Smith et al. is similar to the Lowry assay, since it also depends on the conversion of Cu 2+ to Cu + under alkaline conditions (see Chapter 1).The Cu + is then detected by reaction with BCA. The two assays are of similar sensitivity, but since BCA is stable under alkali conditions, this assay has the …
