Fig 3. Determination binding kinetics by quartz crystal microbalance measurements.
Specificity and affinity of scDb-SpGC3, scDb-SpGC3Fab, and scDb-SpGC3FabRR for human and mouse serum IgG, Fc Fragments, and Fab fragments were determined by QCM measurements at pH 7.4. Two-fold dilutions were added, starting at a concentration of 1,000 nM.
