Biological Activity
The activity is assayed on anti-proliferation and anti-migration of endothelial cells in vitro and anti-angiogenesis in vivo. The specific activity of anti-migration of endothelial cells in vitro is 55,000 Units/mg.

Description
Angiostatin Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 259 amino acids and having a molecular mass of approximately 30.0 kDa.
The Ang K1-3 is purified by proprietary chromatographic techniques.

Lyophilized from a 0.2¦Ìm filtered concentrated (1.0mg/ml) solution in 20mM NaAc, pH5.5, 4% mannitol.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Protein content
Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 2.08 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a standard solution of Ang K1-3 as a Reference Standard.

Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
We recommend to briefly centrifuge the vial 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¡ãC. Further dilutions should be made in appropriate buffered solutions.

Source
Escherichia coli.

Stability
The lyophilized Angiostatin K1-3 is stable for several weeks at 2-8¡ãC, but should be kept at -20¡ãC for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8¡ãC. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20¡ãC to -70¡ãC.
Avoid repeated freeze/thaw cycles.

Synonyms
Angiostatin, Angiostatin Kringles 1-3, Ang K1-3.
