Figure 4. Sandwich ELISA-like detection of CBD.

Figure 4.

(a) CA-14 was immobilized on a plate and the CBD-induced binding of phage-displayed DB-21 was detected by a horseradish peroxidase-conjugated antibody. (b) The detection of CBD spiked in urine and saliva samples. Limits of detection (LoDs = meanblank + 3×(standard deviation of the blank, n=8)) for urine and saliva samples were determined to be ~0.8 nM (~0.25 ng/mL).
