Active Recombinant Human CXCL8 protein

• Cat.No.: CXCL8-17H
• Product Overview: Recombinant Human CXCL8 protein(Ala23-Ser99) was expressed in E.coli.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 23-99 aa
• Form: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
• Bio-activity: Measured by its ability to enhance Bcl2 expression in HCT116 human colon adenocarcinoma cells. 0.01-1ng/mL of Recombinant Human IL-8 can effectively enhance Bcl2 expression.
• Molecular Mass: 8.92 kDa
• Endotoxin: < 1 EU/μg of the protein by LAL method.
• Purity: ≥ 95 % as determined by SDS-PAGE.
• Storage: Store at -20°C.Store the lyophilized protein at -20°C to -80°C up to 1 year from the date of receipt.After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.
• Reconstitution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
