Recombinant Human GDNF

• Description:

  GDNF is a disulfide-bonded homodimeric glycosylated protein of 134 amino acids. The amino acid sequences inferred from rat and human cDNAs are 93% identical. The proteins contain seven conserved cysteine residues in the same relative spacing found in all members of the TGF-beta superfamily of proteins. In embryonic midbrain cultures GDNF promotes the survival and morphological differentiation of dopaminergic neurons and increases their high-affinity dopamine uptake.

• Gene Name:

  GDNF

• Gene Aliases:

  GDNF, Glial cell line-derived neurotrophic factor, hGDNF, Astrocyte-derived trophic factor, ATF
  Recombinant Human Glial-Derived Neurotrophic Factor (GDNF)

• Accession Number:

  P39905

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method.

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

• Function:

  The ED(50) was determined by the proliferation of rat C6 cells is < 0.1 ng/mL, corresponding to a specific activity of > 1.0 x 10^7 units/mg.

• Molecular Weight:

  15

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

  The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

• Appearance:

  Lyophilized Powder

• Formulation:

  Recombinant Glial-Derived Neurotrophic Factor was lyophilized from a 0.2 μm filtered solution in 2.5% glycine, 0.5% sucrose, 0.01% Tween80, 5 mM Glutamic acid, pH 4.5.

• CAS Number:

  9000-83-3
