Residues 31–91 of TREM2 are crucial for its interaction with oAβ_1–42. a Schematic representation of different fragments of sTREM2-Fc. b Immunoblotting of sTREM2-Fc fragments in the conditioned medium or cell lysate from HEK 293 T cells. (c and d) Bar graphs showing the quantification of Western blots from panel B (n = 3, one-way ANOVA). e The purified Fc and sTREM2-Fc fragments were analyzed by silver staining. (f and g) Solid phase binding assay showing the binding affinity of oAβ_1–42 to sTREM2-Fc fragments (n = 3, two-way ANOVA). Data information: Data represent mean ± SD. **, p < 0.01; ***, p < 0.001
