Catalog #: CYT-318
Description:
Visfatin Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 348 amino acids and having 11 N-terminal flag tag The total molecular mass is 39.6 kDa (calculated). The amino acid sequence of the recombinant human Visfatin is 100% homologous to the amino acid sequence Pro27-Glu363 of the human Visfatin.
The Visfatin is purified by Flag-affinity chromatography.

Applications:
Western Blot.
Purity:
Greater than 95.0% as determined by SDS-PAGE.
Solubility:
Add 20mM Tris, 20mM NaCl, pH 7.5 to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
Formulation:
Filtered (0.4 µm) and lyophilized from 0.5 mg/ml in 20mM Tris, 20mM NaCl, pH 7.5.
Stability:
Lyophilized Visfatin although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution Visfatin should be stored at 4 °C between 2-7 days and for future use below
-18 °C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Physical Appearance:
Filtered White lyophilized (freeze-dried) powder.
