Purification
> 95 % by SDS-PAGE and 90% by SEC-HPLC analyses.
Endotoxin
Less than 0.1 EU/ug of rRtVEGF120, Yeast as determined by LAL method.
Bioactivity
Fully biologically active when compared to standard. Measured in a cell proliferation assay using HUVEC human umbilical vein endothelial cells. The ED50 for this effect is 2-10 ng/ml.
Storage Conditions
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.12 months from date of receipt, -20 to -70 °C as supplied.1 month, 2 to 8 °C under sterile conditions after reconstitution.3 months, -20 to -70 °C under sterile conditions after reconstitution.
Calculated Molecular Weight
Theoretically as a disulfide-linked homodimeric protein, the product consists of two 121 amino acid polypeptide chains. As a result of glycosylation, it migrates to at least two bands with molecular weights ranging from 18.5 kDa in SDS-PAGE under reducing conditions.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
