Recombinant Rat SDF-1 a (rRt SDF-1a/CXCL12 )

Recombinant Rat SDF-1 a (rRt SDF-1a/CXCL12 )

• CAS Number: 9000-83-3
• Source: Escherichia coli.
• Purity: > 97 % by SDS-PAGE and HPLC analyses.
• Bioactivity: Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human peripheral blood monocytes is in a concentration range of 50-100 ng/ml.
• Molecular Weight: Approximately 7.9 kDa, a single non-glycosylated polypeptide chain containing 68 amino acids.
• Storage Conditions: This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.
• Formulation: Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.
• Host or Source: Rat
