Formulation | Lyophilized from a 0.2 μm filtered solution in PBS with 5% Trehalose and 5% Mannitol. |
Reconstitution | It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis. |
Background | CXCL12, also known as SDF-1, is a CXC chemokine that interacts with CXCR4. SDF-1 alpha and SDF-1 beta are alternatively spliced isoforms of CXCL12. SDF-1 beta has an additional 4 amino acids at the carboxy-terminus. |
