Description

General description

Recombinant, human angiostatin expressed in E. coli as a single, nonglycosylated polypeptide chain containing 259 amino acids. Represents a proteolytic fragment containing the first three kringle structures of plasminogen. Acts as a specific inhibitor of endothelial cell growth and angiogenesis. Displays increased inhibitory activity (ED₅₀=70 nM) relative to kringles 1-4 (ED₅₀=135 nm).

Physical form

Lyophilized from 20 mM Sodium Acetate, 4% Mannitol, pH 5.5.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C.
