Abstract: This invention provides: novel proteins, which are homologous to the first Kunitz domain (K1) of lipoprotein-associated coagulation inhibitor (LACI), and which are capable of inhibiting plasmin; uses of such novel proteins in therapeutic, diagnostic, and clinical methods; and polynucleotides that encode such novel proteins.

Abstract: In order to obtain a novel binding protein against a chosen target, DNA molecules, each encoding a protein comprising one of a family of similar potential binding domains and a structural-signal calling for the display of the protein on the outer surface of a chosen bacterial cell, bacterial spore or phage (genetic package) are introduced into a genetic package. The protein is expressed and the potential binding domain is displayed on the outer surface of the package. The cells or viruses bearing the binding domains which recognize the target molecule are isolated and amplified. The successful binding domains are then characterized. One or more of these successful binding domains is used as a model for the design of a new family of potential binding domains, and the process is repeated until a novel binding domain having a desired affinity for the target molecule is obtained.
