Figure 4From: Estimation of affinities of ligands in mixtures via magnetic recovery of target-ligand complexes and chromatographic analyses: chemometrics and an experimental modelHPLC-MS-SIM analyses of the concentrated extract of bound ligands from the PMFS of BCHA alone as the ligand of interest. The PMFS was that used in Figure 3. The component in the concentrated extract with m/z = 116 and a retention time of 1.4 min was a contaminant from SMPP.Back to article page
