Actin Binding Proteins (ABPs)

Our quality is your guarantee.

Actin-binding proteins control filament nucleation, barbed-end dynamics, severing, depolymerization, stabilization, cross-linking and force generation. They are essential tools for mechanistic in vitro reconstitution, TIRF single-filament assays, bulk kinetics, co-sedimentation, and structure–function studies.

Scientific-grade ABPs for quantitative actin research

Actin-binding proteins (ABPs) from Hypermol are quality tested and validated for reliable performance and best results. Use defined ABP activities to tune network architecture and kinetics: branching versus linear growth, filament turnover, bundling/cross-linking, and coupling to adhesion or membrane systems.
