    a) GUVs labeled with Rhodamine PE (red channel) were incubated with Aβ-40 doped with Hylite-488 Aβ-40 (green channel) to monitor binding of the peptide within 1 hour (early phase). Early binding of Aβ-40 was observed in the case of PI, DOPG, <t>DOPC/BSM,</t> and DOPC/PIP2 membrane. No binding of Aβ-40 seen on <t>DOPS</t> and <t>DOPC/DOPE</t> membranes. b) Average fluorescence binding intensity of Aβ-40 on membranes with different head groups. The number of GUVs screened for each condition in the box plots is n= 35 from three independent experiments. The symbol **** indicates p values of ≤ 0.0001, calculated by one-way ANOVA followed by Bonferroni’s multiple comparison test. c) ThT fluorescence assay to monitor the effect of lipid head groups on the aggregation kinetics of Aβ-40. d) Effect of lipid head groups on the growth rate of Aβ-40 aggregation quantified within in the early phase of aggregation time scales i.e., 30 minutes). e) Effect of lipid head groups on the sustained aggregation of Aβ-40 during the late phase (saturation phase) of aggregation kinetics, i.e., 6 hours). +/- refer to the net charge on the membrane (i.e, negative or zwitterionic).

    Millipore mpz/p0 cell membrane myelin, chicken polyclonal
    Useful antibodies to characterize human Schwann cells (hSCs) and non-glial cells established in cell culture. These antibodies were validated using traditional adult nerve-derived hSC monocultures. Staining with NGFR, Sox10, and S100B antibodies, alone or together with fibronectin, SMA (α-smooth muscle actin), and FAP (fibroblast activation protein/seprase) antibodies, is recommended for the initial characterization of hSCs and non-glial cells. We have not found a ubiquitous non-glial cell marker. Protocol 1C is suitable for staining with all antibodies except for anti-O1 and anti-O4, which can be accomplished only in live cells (Protocol 1B). A 1:200–1:500 starting dilution is suitable for most antibodies; the optimal concentration should be determined by the end user in the target cells. (*) Indicates that the antibodies are produced from hybridoma cell lines. MBP: myelin basic protein; MAG: myelin-associated glycoprotein; MPZ: myelin protein zero; GFAP: glial fibrillary acidic protein.

    Steady-state anisotropy measurements were performed on different membrane conditions that include membranes with variable DOPC/BSM content keeping cholesterol constant (2:6:2, 4:4:2, 6:2:2), along with single lipid membrane compositions like DOPC, BSM, LPI, DPPC, and multicomponent membranes of myelin and DOPC/BSM/Chol/PIP 2 incubated with Aβ-40. Controls without Aβ-40 for each membrane condition were normalized to 100, denoted by the horizontal red line traversing the plot. The data shown represent the ± SEM extracted from three independent experiments.

    Techniques:

    Useful antibodies to characterize human Schwann cells (hSCs) and non-glial cells established in cell culture. These antibodies were validated using traditional adult nerve-derived hSC monocultures. Staining with NGFR, Sox10, and S100B antibodies, alone or together with fibronectin, SMA (α-smooth muscle actin), and FAP (fibroblast activation protein/seprase) antibodies, is recommended for the initial characterization of hSCs and non-glial cells. We have not found a ubiquitous non-glial cell marker. Protocol 1C is suitable for staining with all antibodies except for anti-O1 and anti-O4, which can be accomplished only in live cells (Protocol 1B). A 1:200–1:500 starting dilution is suitable for most antibodies; the optimal concentration should be determined by the end user in the target cells. (*) Indicates that the antibodies are produced from hybridoma cell lines. MBP: myelin basic protein; MAG: myelin-associated glycoprotein; MPZ: myelin protein zero; GFAP: glial fibrillary acidic protein.
