Endostatin is a naturally occurring 20 kDa polypeptide derived from the C-terminal portion of type XVIII collagen. It functions as an anti-angiogenic cytokine that is expressed in various organs with the highest levels in liver, lung and kidney. Endostatin inhibits angiogenesis by blocking the pro-angiogenic activities of VEGF and FGF-basic. Recombinant human Endostatin produced in Pichia Pastoris is a single, glycosylated polypeptide consisting of 184 amino acid residues and having a total molecular mass of 20,000 Dalton. is a 20.2 kDa protein. The Endostatin was purified using proprietary chromatographic techniques.

Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored dessicated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at –20°C. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze / thaw cycles.
