Figure 5From: Cognate peptide-receptor ligand mapping by directed phage display Panning of the HA fragment phage library with pAb 07431. The HA fragment phage display library was selected against the anti-haemagglutinin pAb 07431 or wells coated with BSA only (no antibody). The Eluted phage was quantified after each round of panning by plaque assay.Back to article page
