Human CXCL9 Protein, His Tag

CXCL9 is a small cytokine belonging to the CXC chemokine family that is also known as monokine induced by gamma interferon (MIG). CXCL9 is a chemokine that plays a role in immune responses, it can induce chemotaxis, promote differentiation and proliferation of leukocytes, and cause tissue extravasation. CXCL9 regulates immune cell migration, differentiation and activation by binding to CXCR3 receptor, such as CTLs, NK cells, NKT cells and macrophages. CXCL9 also participates in Th1 polarization and IFN-γ response.

This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 20.7 kDa. The protein migrates as 17-20 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).
