Mouse Periostin/OSF-2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asn24-Gln811.[Accession | Q62009-1]
分子量大小(Molecular Weight)
The protein has a predicted MW of 88.7 kDa. Due to glycosylation, the protein migrates to 90-95 kDa based on Tris-Bis PAGE result.
内毒素(Endotoxin)
Less than 1EU per μg by the LAL method.
纯度(Purity)
> 95% as determined by Tris-Bis PAGE > 95% as determined by HPLC
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)
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
储存条件 The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first usedand avoid repeated freeze-thaw cycles. 注意事项 1.Please operate with lab coats and disposable gloves,for yoursafety. 2.This product is for research use only.
