恺佧生物科技（上海）有限公司

表达区间及表达系统（Source）	Recombinant Mouse IL-5 R alpha/CD125 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp18-His339 [Accession \| P21183].
分子量大小（Molecular Weight）	The protein has a predicted MW of 37.7 kDa. Due to glycosylation, the protein migrates to 50-60 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 1 EU per μg by the LAL method.
制剂（Formulation）	Supplied as 0.22μm filtered solution in 20mM Tris, 500mM NaCl (pH 7.4).
存储（Storage）	Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
