Fig. 2From: Lysophosphatidic acid (LPA)-antibody (504B3) engagement detected by interferometry identifies off-target bindingFSA configuration to analyze by CIR. Lipid solutions (six to seven different concentrations each) were divided into two aliquots: one with 504B3 antibody in PBS to form the binding sample; and one with PBS only to prepare an RI-matched non-binding reference solution. The binding signal is determined by RI change between the reference and the sampleBack to article page
