Glial-Derived Neurotrophic Factor Human Recombinant ( GDNF Human )

Data sheet

Formulation

GDNF was lyophilized from a 0.2um filtered concentrated solution in 1PBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized Glial Derived Neurotrophic Factor in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Glial derived Neurotrophic Factor Human Recombinant produced in E.Coli is a non-glycosylated disulfide-linked homodimer containing 2 x 135 amino acids and having a total molecular mass of approximately 30kDa. GDNF is purified by proprietary chromatographi

Protein Background

GDNF promotes the survival and differentiation of dopaminergic neurons in culture, and is able to prevent apoptosis of motor neurons induced by axotomy. The encoded protein is processed to a mature secreted form that exists as a homodimer. The mature form

Expression host

Escherichia Coli.

Synonyms

ATF1, ATF2, HFB1-GDNF, GDNF.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Glial-derived Neurotrophic Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GDNF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage
