表达区间及表达系统（Source）	Recombinant FITC-Labeled Human Siglec-2/CD22 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Asp20-Arg687 [Accession \| P20273-1].
分子量大小（Molecular Weight）	The protein has a predicted MW of 101.9 kDa. Due to glycosylation, the protein migrates to 130-140 kDa based on Bis-Tris PAGE result.
波长（Wavelength）	Excitation Wavelength: 490 nm Emission Wavelength: 520 nm
纯度（Purity）	> 95% as determined by Bis-Tris PAGE
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
制剂（Formulation）	Supplied as 0.22μm filtered solution in PBS (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.
