Purity: >95% by SDS-PAGE and HPLC analyses.
Biological Activity: Fully biologically active when compared to standard. The specific activity determined by an assay on
anti-proliferation and anti-migration using endothelial cells in vitro and anti-angiogenesis in vivo is 5.5 × 105 IU/mg.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: Lyophilized from a 0.2μm filtered concentrated solution in 20mM NaAc, pH5.5, 4% mannitol.
Endotoxin: Less than 1EU/μg of rHuAngiostatin K1-3 as determined by LAL method.
Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the
bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a
concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and
stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
Storage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage,
preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For
maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to
-70°C. Avoid repeated freeze/thaw cycles.
Usage: This material is offered by Shanghai Corning Bio-Tech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
Human Angiostatin K1-3
Angiostatin K1-3 is a ~30 kDa fragment of plasminogen that has been shown to act as a potent inhibitor of angiogenesis and
tumor growth in vitro and in vivo. Recombinant angiostatin is expressed in E. coli.
