Figure 1. Percent positive clones obtained from second-generation library. Positive clones were defined as clones with an ELISA signal at least two-fold greater than the negative control.

(a) Results from four rounds of panning using immunotube based selection.
(b) Results from a single round of flow-based selection. Samples were collected after 3, 4, 5, 6 and 7 hrs and during the regeneration step (R). Total phage recovered are total titers from each sample collected.
