  1. aNumber of phage pfu incubated with the antigens immobilized on the nitrocellulose strip
  2. bNumber of phage pfu eluted after the incubation above
  3. cPercentage of bound phage calculated as the ratio phage output/phage input × 100
  4. dRatio of the percentage of bound phage at round n vs the percentage of bound phage at round n–1
