表达区间及表达系统（Source）	Recombinant Cynomolgus GFRAL/GFR alpha-like Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Gln20-Glu351 [Accession \| XP_015304775.2].
分子量大小（Molecular Weight）	The protein has a predicted MW of 40.7 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
纯度（Purity）	> 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
制剂（Formulation）	Lyophilized from 0.22μm filtered solution in 20mM PB, 0.4M NaCl (pH 6.0). Normally 8% mannitol is added as protectant before lyophilization.
重构方法（Reconstitution）	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 20mM PB, 0.4M NaCl (pH 6.0).
存储（Storage）	-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
