Changes in quartz crystal microbalance resonance frequencies in response to antibody binding. 5-Hydroxytryptophan-functionalized quartz crystals were exposed to polyclonal (pAb) antibodies raised against 5-hydroxytryptophan (5-HTP), anti-rabbit polyclonal antibodies against immunoglobulin-G (IgG), or bovine serum albumin (BSA). The large decrease in mean QCM frequency after 5-HTP pAb exposure suggests selective binding of this antibody relative to IgG pAb or BSA. Error bars represent SEMs for N = 3 samples [F(2,6) = 610; P < 0.001]; ∗∗ indicates P < 0.01 vs IgG pAb and BSA.
