WebHere, we systematically compared the two methods by trying 4 SDS-PAGE/RPLC and 3 high-/low-pH RPLC different workflows for a higher sensitivity in protein identification. Totally … Webcouples high-pH RPLC and low-pH RPLC for intact protein separation. 22. In Baghdady’s work, microflow RPLC columns were used in both dimensions and two sample storage loops were used for online coupling. In the second dimension low pH RPLC separation, a very steep gradient (<1 min) was utilized which has been reported to enable the injection of chiropractic cracking
