PET surface affinity assay. a Replica-membrane of PET surface treated with increasing amounts of the purified peptide BaCBM2-Bs2-StrepII in four replicas. Each spot of the scanned membrane was cut out computationally in order to avoid background signals in densitometric analysis. b Densitometric analysis of membrane spots from a using ImageJ (26)
