Detection of PSA in 20% serum using a lower nanoswitch concentration of 400 pM. Average bound intensity per lane as a function of concentration for PSA in 20% serum. Results are for 4 μL of serum (i.e., 20 μL of diluated sample) run in one gel lane (blue), 8 μL of serum run across two gel lanes (red), or 100 μL of serum run across multiple gel lanes. Error bars are the SD, with the background given by the dashed line for four replicates at 100 fM and 20 replicates at 0 fM.
