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 map to 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

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 34 33 32 34 33 0.83 2.5% Sample 2 241 265 259 244 252 9.08 3.6% Sample 3 440 440 458 462 450 18.45 4.1% Lots Lot 1 (pg/ml) Lot 2 (pg/ml) Lot 3 (pg/ml) Lot 4 (pg/ml) Mean (pg/ml) Standard Deviation CV (%) 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 34 33 32 34 33 0.83 2.5% Sample 1 34 33 32 34 33 0.83 2.5% Sample 2 241 265 259 244 252 9.08 3.6% Sample 2 241 265 259 244 252 9.08 3.6% Sample 3 440 440 458 462 450 18.45 4.1% Sample 3 440 440 458 462 450 18.45 4.1%
