Chemokines are a family of small cytokines,or proteins secreted by cells,with a molecular mass between 8 and 10 kDa. Members of the chemokine family are divided into four groups depending on the location of their first two cysteine residues. The major role of chemokines is to act as a chemoattractant to guide the migration of cells. GenScript offers a comprehensive catalog of chemokine proteins with excellent lot-to-lot consistency,superior activity and significantly low endotoxin levels. Our goal is to provide scientists quick and easy access to research tools that advance innovation and discovery.
