Patent ID: 7560427

Claim:
A method for prevention of platelet aggregation in a subject in need thereof, said method comprising administering to said subject an RGD-enriched gelatine, at least 80% of the sequences of said RGD-enriched gelatine consisting of one or more parts of one or more native human collagen sequences each native human collagen sequence part having a length of at least 30 amino acids, said RGD-enriched gelatine having a molecular weight of about 30 kDa to about 200 kDa, and in which RGD-enriched gelatine the number of RGD motifs is an integer and the percentage of RGD motifs related to the total number of amino acids is at least 0.4 and if the RGD-enriched gelatine comprises 350 amino acids or more, each stretch of 350 amino acids contains at least one RGD motif, wherein said method prevents platelet aggregation.
