About ChemoTactics

ChemoTactics was founded in 2013 by structural biologists and pharmacologists at UC San Diego. Our mission is to provide the chemokine research community with affordable high-quality chemokine reagents. 

We specialize in the efficient production of high-quality human chemokines for research scientists worldwide. Our products include both unmodified and biotinylated chemokines for flow cytometry, in vivo, drug development, imaging, cell characterization and other techniques.

Our expertise lies in recombinant chemokine production which can also be applied to other signaling proteins with high levels of activity. Our  technology was utilized to help solve the multiple crystal structures of CXCR4 [7].
