Figure 1. Binding of specific antibodies hAB2367 to β1ADR as measured by optical density (OD) at 450 nm versus the amount of MF (membrane fraction) and MF+Polymer preparations added to a well (see Procedure, Enzyme-linked immunosorbent assay). A, B, C, D stand for MF+Polymer preparations with polymer concentrations 0.5%, 0.25%, 0.125% and 0.0625%, respectively. MF stands for a preparation of membrane fraction. The results of ELISA are provided for polymers with high (UltrasoluteTM Amphipol 17), moderate (AASTY 11-55) and low (DIBMA 10) relative solubilization value (RSV).
