Detailed product information

Background information

Pleiotrophin (PTN) is a heparin-binding non-glycosylated growth factor containing 136 amino acids. The protein is mainly found in tissue of the central nervous system. The concentration of Pleiotrophin reaches its’ peak in the late fetal state and is maintained in later stages of life. Pleiotrophin is thought to play a role in the growth and the maturation of the brain. If applied to neurons in cell culture it supports the growth of neurites. It was also suggested that Pleiotrophin might play a role in the pathogenesis of neuroblastomas.

Quality description

cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
