Lyophilized after extensive dialysis against PBS. Endotoxin Level
<0.2 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Platelet factor-4/CXCL4 (HEK293-expressed) (rHuPF-4/CXCL4) to 100 μg/mL using ddH2O or PBS. Storage & Stability
Lyophilized recombinant Human Platelet factor-4/CXCL4 (HEK293-expressed) (rHuPF-4/CXCL4) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
PF-4/CXCL4 is a member of the CXC chemokine family produced by cells of the megakaryocytic lineage. CXCL4 has antiheparin activity, responsible for the important role of CXCL4 in the regulation of coagulation processes. CXCL4 has exhibits antiangiogenic properties in vitro and in vivo and inhibits tumor neovascularization through a variety of mechanisms[1]. |
