Traditional SDS-PAGE method of protein screening in soybeans is laborious, time-consuming and involves toxic chemicals that are hazardous for the researchers and the environment. High-throughput protein profiling electrophoresis
(PPE) using protein chips has advantages over traditional SDS-PAGE because it saves time and labor, is highly accurate,
and involves simple data analysis. Indeed, the electropherograms and virtual gel images generated by Caliper LabChip can be directly converted to Excel files, thus minimizing the time required and reducing the error of manual protein band scoring.
