Extended Data Fig. 5: Detection of signals sampled at 500 kHz.
From: Label-free detection and profiling of individual solution-phase molecules
Single diffusion events of <1 nm protein, Myc-tag, are resolvable with 2 μs temporal resolution. Representative single Myc-tag events collected with 500 kHz acquisition frequency. Data collected using cavity two at a concentration of 1 pM.
