Recombinant Human GDNF Family Receptor alpha-1/GFRA1 is produced with our mammalian expression system in human cells. The target protein is expressed with sequence (Asp25-Lys429) of Human GFRA1 fused with a polyhistidine tag at the C-terminus.
纯度
> 95 % as determined by reducing SDS-PAGE.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Glial Cell Line-Derived Neurotrophic Factor Family Receptor alpha-1 (GDNFRalpha1) is a glycosylphosphatidylinositol (GPI) linked cell surface protein belonging to GDNF-family receptor alpha subtype which consists of at least four members. GFRalpha1and GFRalpha2 are the cognate co-receptor for the neurotrophic factor neurturin mediating the NRTN-induced autophosphorylation and activation of the RET tyrosine kinase receptor. Soluble GFRalphas released enzymatically from the cell surface by phosphatidylinositol phospholipase C, as well as recombinantly produced soluble GFRalpha1, can also bind with high affinity to GDNF and trigger the activation of Ret tyrosine kinase. Human GFRalpha1 shares 93% amino acid identity with mouse GFRalpha1.The expression of the various GFRalphas are differentially regulated in the central and peripheral nervous system, suggesting complementary roles for the GFRalphas in mediating the activities of the GDNF family of neurotrophic factors.
