Fig 1. Enrichment of binding phages and phage recovery after in vitro biopanning rounds against the 4T1 cell line using C7C and 12-mer libraries.

(A) Enrichment of binding phages for each biopanning round. The phage titer was assessed between rounds and compared between the two modified panning procedures. (B) Phage recovery yield of internalized phages after consecutive selection step. The phage recovery of both libraries was calculated by dividing the number of recovered plaque-forming phages (output) by the input number of plaque-forming phages.
