METHODS: Using CHO cells which high express human CD59 as target cells, the phage 12 peptide library was screened for 5 rounds by competitive binding test.

"If our main competitive advantage was paper and binding, I'd say we're in a world of hurt," Kilburn said.

Competitive INHIBITION Competitive inhibitors compete with substrate for an enzyme's active site, lowering the enzyme's likelihood of binding substrate and slowing the observed reaction velocity.
