Description：Recombinant Human GDNF Protein is produced by mammalian expression system and the target gene encoding Phe20-Ile211 is expressed with a Fc, 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：GDNFAlternative Names：Glial cell line-derived neurotrophic factor; hGDNF; Astrocyte-derived trophic factor; ATF Entrez Gene (Human)： 2668; SwissProt (Human)： P39905; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：FPLPAGKRPP EAPAEDRSLG RRRAPFALSS DSNMPEDYPD QFDDVMDFIQ ATIKRLKRSP DKQMAVLPRR ERNRQAAAAN PENSRGKGRR GQRGKNRGCV LTAIHLNVTD LGLGYETKEE LIFRYCSGSC DAAETTYDKI LKNLSRNRRL VSDKVGQACC RPIAFDDDLS FLDDNLVYHI LRKHSAKRCG CIVDDIEGRM DEPKSCDKTH TCPPCPAPEL LGGPSVFLFP PKPKDTLMIS RTPEVTCVVV DVSHEDPEVK FNWYVDGVEV HNAKTKPREE QYNSTYRVVS VLTVLHQDWL NGKEYKCKVS NKALPAPIEK TISKAKGQPR EPQVYTLPPS REEMTKNQVS LTCLVKGFYP SDIAVEWESN GQPENNYKTT PPVLDSDGSF FLYSKLTVDK SRWQQGNVFS CSVMHEALHN HYTQKSLSLS PGKHHHHHHDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
