Thermo Scientific™ Pierce™ Rapid Gold BCA Protein Assay Kit is a two-component, high precision, detergent-compatible assay optimised to measure (at 480 nm) total protein concentration compared to a protein standard curve of known concentrations. The Pierce™ Rapid Gold BCA Protein Assay uses the same copper-chelating technology as the well-known traditional Pierce™ BCA Protein Assay and provides comparable accuracy but with a 5 minute, room temperature incubation and measured at 480 nm. This improvement eliminates the need to wait or expose the samples to elevated temperatures for a fast time to results.

Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of 2 chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.
