Chemokine (C-C motif) ligand 14 (CCL14), also known as HCC-1, is a small cytokine belonging to the CC chemokine family. It is expressed in various tissues including spleen, bone marrow, liver, muscle, and gut.1 CCL13 activates monocytes, but does not induce their chemotaxis. CCL14 is of recent interest because of its natural ability to bind to and signal through the human immunodeficiency virus type-1 (HIV-1) co-receptor, CC chemokine receptor 5 (CCR5).2
>97% by SDS-PAGE and analyzed by silver stain.
<0.01EU/µg as determined by the LAL method
The biological activity of Human HCC-1 was determined by its ability to chemoattract cultured human monocytes or BaF/3 hCCR1 transfected cells. The expected ED50 for these effects are typically 5 - 15 μg/ml or 0.2 - 0.8 μg/ml, respectively.
