表达区间及表达系统（Source）	Recombinant Human KIR2DL4/CD158d Protein is expressed from HEK293 with hFc tag at the C-terminus. It contains Trp22-His242 [Accession \| Q99706-1].
分子量大小（Molecular Weight）	The protein has a predicted MW of 50.24 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result.
纯度（Purity）	> 90% as determined by Bis-Tris PAGE
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
制剂（Formulation）	Supplied as 0.22 μm filtered solution in 20mM PB, 500mM NaCl, 200mM L-Arginine (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.
