| Description: | A random 12-peptide library was screened against Erysipelothrix rhusiopthiae and porcine circovirus 2 recombinant Cap protein and the selected peptides were used for detecting the corresponding pathogens quickly and effectively. P5 (HFFKWHTRTNDQ) with the characteristics of polystyrene plate (PS) binding target-unrelated peptides (TUPs), was selected from the library. It has been found that P5 has been isolated repeatedly in other research groups using different targets. Then, the peptide phage clone was identified as the PS binding TUP phages by phage-ELISA and elution titration. In addition, the phage was not propagation-related TUP. |
