Description of Human PF-4 (CXCL4)

Recombinant Human PF-4 (CXCL4) produced in E. coli is a 7.8 kDa single, non-glycosylated polypeptide chain containing 70 amino acids.


Biological Activity

The ED50 of 5-15 g/ml was determined by its ability to inhibit human FGF basic dependent proliferation of NR6R3T3 mouse fibroblasts.



We recommend a quick spin followed by reconstitution in water to a concentration at least 100g/ml. Do not vortex. This solution can be stored at 2-8C for up to 1 week or in working aliquots at -20C to -80C. Working aliquots should be at the highest practical concentration. For long term storage we recommend to add at least 0.1% HSA (order number: or or BSA.



Lyophilized Human PF-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution PF-4 should be stored at 4C between 2-7 days and for future use below -18C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid repeated freeze-thaw cycles.
