Heptapeptides binding to AIV subtype H9N2 and streptavidin selected from the phage display random peptide library.

Rounds of panning	Heptapeptide sequences	Frequency of sequences (%)
4th round	NDFRSKT	47
	QHSTKWF	10.5
	LPYAAKH	5
	ILGDKVG	5

Panning of Streptavidin
3rd round Streptavidin	HPQFLSL	55
	GLYNHPQ	27
	Unrelated sequences	18

After 4 rounds of selection and amplification 20, 35 and 35 individual clones from the 2^nd, 3^rd and 4^th rounds, respectively, were sequenced for AIV whereas 20 clones were sequenced from the 3^rd round of panning against Streptavidin.
