Description

BF 227 is a candidate for an amyloid imaging probe for PET, with a Ki of 4.3 nM for Aβ1-42 fibrils.

IC50 & Target

Ki: 4.3 nM (Aβ1-42)[1].

In Vitro

BF-227 has a high binding affinity for Aβ1-42 fibrils. The Ki value for Aβ1-42 fibrils in competitive binding assay using [125I]BF-180 is 4.3±1.3 nM in BF-227 (Kd value of [125I]BF-180: 10.8±1.5 nM)[1]. [11C]BF-227 is a PET tracer. The AUC for BF-227 (0.994) is much higher than that for FDG (0.839), indicating that BF-227 is more sensitive as well as more specific than FDG in diagnosing AD[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
