Product Description: The product contains the polyhedrin protein co-crystalized with Human CCL13. A member of the CC sub-family of chemokines, CCL13 signals primarily via the CC chemokine receptors CCR2B and CCR3. It is a chemoattractant for monocytes, lymphocytes, basophils and eosinophils. It is also involved in the accumulation of leukocytes at the sites of allergic and non-allergic inflammation. The activity of this protein can be induced via several inflammatory cytokines, including interleukin-1 and TNF-α.
