Figure 6. Phages selected against ErbB3. (A) To analyze the diversity displayed by phages binding ErbB3 and TNF-α, 12 clones for ErbB3 and 15 clones for TNF-α, all obtained in the second panning assay, were isolated and analyzed by phage ELISA, as described in Materials and Methods. A helper phage was used as negative control. Solid-colored bars indicate positive clones. (B) Phagemids were obtained from positives clones, sequenced and analyzed using IgBlast.³⁵
