Protein purification is an ever-vital approach for each academia and industry. This paper mainly reviews and discusses one of the center contents of proteomics, the latest advances in separation technology for protein components focusing on five different methods. The MCPA system is an economically amazing invention for protein therapy researchers to purify samples. Because of the excessive protease interest of Ulp1 toward SUMO fusion, excessive protein products may be done inside 1/2 of an hour through this method. The magnetic separation strategies will offer a higher method of protein purification withinside the close to imminent because of a few advantages. The evaluation established that the ATPS technique became a cost-effective, time-saving (30 min), and high-recuperation approach that can be scaled up for commercial purposes. Herein, ATPS may be an ability approach for the purification of single-step separation and keep away from multistep purification just like the chromatography technique. Therefore, our recent reviews provide a capable technique for competent protein purification.
