• Product Overview: Recombinant Human/Feline CXCL12 (Accession # BAA28602) Ser19-Met93 was produced in E. coli-derived.

Specification

• Source: E. coli
• Species: Human/Feline
• Predicted N Terminal: Ser19
• Form: Lyophilized from a 0.2 µm filtered solution in PBS with BSA as a carrier protein.
• Bio-activity: Measured by its ability to chemoattract BaF3 mouse pro-B cells transfected with mouse CXCR4.The ED50 for this effect is typically 0.15 - 0.6 µg/mL.
• Molecular Mass: Recombinant Human/Feline CXCL12 has a calculated MW of 8.8 kDa.
• Purity: >97%, by SDS-PAGE under reducing conditions and visualized by silver stain.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
• Reconstitution: Reconstitute at 10 µg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
