Interesting, though complex, signal amplification strategy using Nanobodies coupled to peroxidase -> added Glucose Peroxidase -> (reaction glucose -> H2O2) -> tyramide-based signal amplification -> fluorophore deposition.

@domhenri Wow, those numbers are depressing.

Figure 3 should scare everyone who uses antibodies (and hopefully spur them to sanity-check their stainings with additional techniques).
