		Technical Data
G2036-02B	Glial Derived Neurotrophic Factor (GDNF) Recombinant, Human	2ug 10ug 100ug

Growth Factors, Cytokines

Storage: -70°CShipping: Blue Ice

This factor was found initially in conditioned medium of the rat B49 glial cell line. GDNF is a disulfide-bonded homodimeric glycosylated protein of 134 amino acids. The proteins contain seven conserved cysteine residues in the same relative spacing found in all members of the TGF-beta superfamily of proteins. The human GDNF gene has been mapped to chromosome 5p13.1-p13.3. Related factors are Neurturin, Persephin, and Artemin. Collectively they are being referred to as GDNF family ligands.

Endotoxin: <0.01ng/ug or <0.1EU/ug as per LAL
