TagC-terminal His-tag
Purity
>90%
Purity Determined BySDS-PAGE under reducing conditions and visualized by Coomassie blue staining
Molecular Weight (kDa)
Recombinant protein product has a calculated molecular mass of 22 kDa. Due to the abundant glycosylation, it migrates as approximately 26 kDa extra protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions.
Format
Liquid
Formulation
Filtered solution in 15 mM Na2HPO4 (pH 7.4), 5 mM NaH2PO4, 0.5 M NaCl, 750 mM imidazole, 20% glycerol.
Concentration (lot specific)
Refer to the label on the vial for the specific concentration, determined by the Pierce BCA Protein Assay Kit.
Endotoxin Level< 0.5 EU per µg of the protein as determined by the LAL method
Research AreaCardiovascular Disease, Cancer, Inflammation
Shipping TypeBlue ice
Storage-20°C
SDS-PAGE Image
Figure 1. Deglycosylation analysis of purified recombinant proteins. Product was either untreated (Lane 2) or treated with deglycosylation enzymes under native (Lane 3) or denaturing (Lane 4) conditions. Deglycosylation treatment resulted in a mobility shift, indicating that the untreated protein (Lane 2) was glycosylated. Lane 1, protein ladder (kDa).
Activity
Decreasing cell viability significantly. Measured in a cytotoxicity assay using MCF-7 human breast cancer cells. The EC50 for this effect is 40 ng/mL.
Storage/Stability
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Upon arrival, the liquid protein may be stored for 2 weeks at 4°C. For long-term storage, it is recommended to store at -20°C or -80°C in appropriate aliquots. Generally, the shelf life is up to 6 months from the date of receipt at -20°C or -80°C under sterile condition.
