分子别名 (Synonym)
R-spondin-1; RSPO1; CRISTIN3; FLJ40906; RP11-566C13.1; RSPO; R-Spondin1
来源/表达系统 (Source)
Recombinant Human R spondin 1/RSPO1 Protein is expressed from CHO with His tag at the C-Terminus.It contains Arg31-Ala263 [Accession | Q2MKA7].
分子量
The protein has a predicted MW of 27.3 kDa. Due to glycosylation, the protein migrates to 38-42 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 0.05 EU per μg by the LAL method.
纯度 (Purity)
> 95% as determined by Bis-Tris PAGE
制剂 (Formulation)
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). 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.
