Human CXCL4/PF4 PicoKine® Quick ELISA Kit, Carrier-free

• Background:

  Platelet factor 4 (PF4) is a small cytokine belonging to the CXC chemokine family that is also known as chemokine (C-X-C motif) ligand 4 (CXCL4). The PF4 gene was localized on 4q12-q13. Chemokines play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. Platelet factor-4 is a 70-amino acid protein that is released from the alpha-granules of activated platelets and binds with high affinity to heparin. Its major physiologic role appears to be neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair.

  Reproducibility

  To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.

  Lots	Lot 1 (pg/ml)	Lot 2 (pg/ml)	Lot 3 (pg/ml)	Lot 4 (pg/ml)	Mean (pg/ml)	Standard Deviation	CV (%)
  Sample 1	366	303	355	314	335	23.08	6.9%
  Sample 2	1651	1700	1818	1664	1708	63.21	3.7%
  Sample 3	4823	4798	4635	4316	4643	190.36	4.1%
