Chemokines are a family of small cytokines, or proteins secreted by cells. Chemokines induce directed chemotaxis in nearby responsive cells, hence the name chemotactic cytokines. Former names for these proteins include SIS family of cytokines, SIG family of cytokines, SCY family of cytokines, Platelet factor-4 superfamily or intercrines. Some chemokines are considered pro-inflammatory and can be induced during an immune response while others are considered homeostatic.

ProSci has a wide variety of chemokine antibodies. These include antibodies against chemokine coreceptor (CCR), macrophage/monocyte chemotactic protein (MCP), macrophage inflammatory protein (MIP) and many other chemokine proteins. ProSci antibodies are appropriate for ELISA, western blot, and immunohistochemistry (IHC) applications as noted for each chemokine antibody.
