Chemokine ligand is a small cytokine belonging to the CXC chemokine family. It is a protein that is released in large amounts from platelets following their activation. It stimulates various processes including mitogenesis, synthesis of extracellular matrix, glucose metabolism and synthesis of plasminogen activator.
趋化因子配体是属于 CXC 趋化因子家族的小细胞因子。 它是一种在血小板活化后从血小板中大量释放的蛋白质。 它刺激各种过程,包括有丝分裂、细胞外基质的合成、葡萄糖代谢和纤溶酶原激活剂的合成。

Physical Appearance

Sterile Filtered White lyophilized powder.


The CXCL7 protein was lyophilized from a concentrated sterile solution containing no additives.


It is recommended to reconstitute the lyophilized Neutrophil Activating Protein-2in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized NAP-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL7should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.


Greater than 98.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Glu-Leu-Arg-Cys.

Biological Activity

The specific activity as determined by the ability of NAP2 to chemoattract human neurotrophils using a concentration of 1-10ng/ml corresponding to a Specific Activity of 100,000-1,000,000IU/mg.
