Cell panning of scFv library on HEK293-CD9 in three rounds

	1st round	2nd round	3rd round
Phage input (cfua)	1 × 1013	3.16 × 1011	2.08 × 1011
Phage output (cfu)	1.48 × 105	7.40 × 104	6.56 × 105
Recovery rateb	1.48 × 10-8	2.34 × 10-7	3.15 × 10-6

^a cfu: colony forming unit.

^b Recovery rate: output/input ratio used to determine the phage recovery rate of each round.
