Technical Data
Pleiotrophin, Recombinant, Human (PTN, HARP, Heparin Affin Regulatory Peptide)
Molecular Biology Storage: -20CShipping: Blue Ice
Recombinant corresponding to 136aa from human Pleiotrophin expressed in E. coli.

Molecular Weight:

Biological Activity:
To be determined. Pleiotrophin (PTN), also known as Heparin-Binding Growth Factor-8 (HBGF-8) and Heparin-Binding Neurite-Promoting factor (HBNF), is a member of the heparin-binding neurotrophic factor family. Pleiotrophin is important in developmental processes, promoting neurite extension and stimulating cell division in hepatocytes. Pleiotrophin bears structural homology with Midkine (MK). Both Pleiotrophin and Midkine are highly conserved among mammalian species
