Phage selection of hydroxyapatite binding peptides from a randomized 8-mer peptide phage library. (a) Ratio of output/input phages after one, two, three, and four rounds of selection against hydroxyapatite. (b) The ratio of the output/input phage of hydroxyapatite-specific positive clones after the fourth biopanning.
