Stabilizers, Blockers, & Substrates
Market-leading Stabilizers, Blockers & Substrates from BBI
All Surmodics® blockers and stabilisers, and BioFX® substrates are shipped from our Freiburg site to customers across the EU.
We supply Surmodics® blockers and stabilisers alongside BioFX® TMB, ABTS and p-NPP substrates to customers across the EU. Each ready-to-use – or easily diluted – formulation is engineered to do two jobs at once: guard native protein structure for long-term shelf life and seal off assay surfaces to drive down background signal. Whether you’re coating plates, particles or membranes, the result is the same – cleaner baselines, sharper signal-to-noise and reproducible performance from the first run to the last vial.
Blockers
Protein- and protein-free Surmodics blockers—and BBI modified casein—seal open surfaces, slash non-specific binding in blots and lateral-flow tests, and boost signal-to-noise.
Stabilisers & Diluents
StabilCoat™, StabilGuard™, StabilBlock™, and StabilZyme™ lines lock antibodies, antigens or enzymes in native form while simultaneously blocking surfaces – extending kit shelf life.
Substrates
BioFX® HRP and AP substrates (TMB, ABTS, p-NPP) span ultra-fast to ultra-slow kinetics, giving you the dynamic range and sensitivity your ELISA or blot demands.
