Web6 jul. 2024 · Herein, we established an ion-pair reversed-phase×reversed-phase two-dimensional liquid chromatography (IPRP×RP 2DLC) strategy for comprehensive proteomic analysis. Both RPLC separation dimensions were performed at low pH, with trifluoroacetic acid (TFA) and formic acid (FA) as mobile phase addictive, respectively. WebReversed-phase high-performance liquid chromatography (RP-HPLC) involves the separation of molecules on the basis of hydrophobicity. The separation depends on the hydrophobic binding of the solute molecule from the mobile phase to the immobilized hydrophobic ligands attached to the stationary phase, i.e., the sorbent.
