Table 1 Transforming units (TUs) of PLAP binding phage. Transforming units (TUs) of PLAP binding phage after each round of selection. There was an initial fall in the TUs of the eluted phage in comparison to the input phage. There was also a decrease in the TUs of the phage eluted after the second round of selection indicating the decrease in phage binding non-specifically to the beads. For the rounds one and two, the selection was carried out on magnetic beads. For the rounds three and four, the selection was carried out on immunotubes.
