Recombinant Neurturin，Human

Specifications

Product Data
Species	Human
Expression Host	E. coli
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) MARLGARPCGLRELEVRVSELGLGYASDETVLFRYCAGACEAAARVYDLGLRRLRQRRRLRRERVRAQPCCRPTAYEDEVSFLDAHSRYHTVHELSARECACV with polyhistidine tag at the C-terminus.
Tag	His Tag (C-term)
Predicted MW	The protein has a calculated MW of 12.62 kDa. The protein migrates as 13 kDa under reducing condition (SDS-PAGE analysis).
Purity	>98% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4.
Applications	Cell culture
Storage	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. Avoid repeated freeze/thaw cycles.
Bioactivity	Measure by its ability to induce proliferation in SH-SY5Y cells. The ED₅₀ for this effect is <50 ng/mL.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.
Reference Data
UniProt ID	Q99748
Synonyms	NTN, NRTN
Summary	Human Neurturin is a 22 kDa cytokine with 197 amino acid residues. Neurturin belongs to the same TGF-beta (transforming Growth Factors β) family. When Neurturin binds to GFRα-2 (GPI-linked receptor termed GDNF family receptor α-2), this complex activates Ret receptor tyrosine kinase and its downstream signaling pathway.
