SARS-COV-2 Nucleocapsid Protein CTD Domain Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant SARS-COV-2 Nucleocapsid Protein CTD Domain Protein is expressed from E.coli with His tag and Avi tag at the N-Terminus. It contains Gly243-Pro364.[Accession | QHD43423.2]

分子量大小(Molecular Weight)

The protein has a predicted MW of 17 kDa same as 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

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.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

SARS-COV-2 NP CTD Domain on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

背景(Background)

Nucleocapsid protein (N) is the major viral structural component; its main function is to protect and encapsidate the viral RNA forming viral RNP complex. It is encoded by the S segment vRNA and is abundantly expressed in the cytoplasm of infected cells.

分子别名(Synonyms)

Nucleocapsid; NP; NC
