恺佧生物科技（上海）有限公司

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 Tris-Bis PAGE result.
波长（Wavelength）	Excitation Wavelength: 490 nm Emission Wavelength: 520 nm
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
纯度（Purity）	> 95% as determined by Tris-Bis PAGE
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.
