分子别名 (Synonym)
2B4; CD244 antigen; CD244; h2B4; NAIL; NKR2B4; Nmrk; SLAMF4
来源/表达系统 (Source)
Recombinant Human 2B4/CD244/SLAMF4 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus.It contains Cys22-Arg221 [Accession | Q9BZW8-2].
分子量
The protein has a predicted MW of 49 kDa. Due to glycosylation, the protein migrates to 68-75 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 0.1 EU per ug by the LAL method.
纯度 (Purity)
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
制剂 (Formulation)
Lyophilized from 0.22μm filtered solution in 20mM Tris, 150mM NaCl (pH 8.0). Normally 8% trehalose is added as protectant before lyophilization.
重构方法 (Reconstitution)
Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
存储 (Storage)
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
