WebGeneral Quantification: UV-Vis, Bradford and Activity Assays. One way of measuring protein purity is through general quantification of concentration. Although Bradford assays and UV-Vis spectrophotometry are high-throughput and are used in most biochemistry labs across the world, they are relatively basic compared to enzymatic activity assays. WebMay 24, 2016 · SDS PAGE. The RuBisCO obtained from the green juice was analyzed by SDS-PAGE on 15 % (w/v) polyacrylamide gels to confirm its presence and purity. Quaternary structural studies have previously demonstrated that native RuBisCO is a multimeric protein consisting of eight small and eight large subunits [34–36].
