ATF, ATF1, ATF2, HFB1-GDNF, HSCR3

Measure by its ability to induce proliferation in SH-SY5Y cells.
The ED50 for this effect is <10 ng/mL.

Glial cell-derived neurotrophic factor (GDNF) is a protein that, in humans, is encoded by the GDNF gene. GDNF is a small protein that potently promotes the survival of many types of neurons. GDNF, that acts via classical neurotrophic mechanism, has been effective in several pre-clinical models of PD and had some efficacy in parkinsonian patients.

The protein was lyophilized from a solution containing 20 mM sodium citrate, 0.2 MNaCl, pH 3.5.

It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Blue Ice

Lyophilized protein should be stored at -20°C for 1 year.
Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1%
BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months.
