SARS-CoV-2 (COVID-19) Nucleocapsid protein, His Tag
分子別名(Synonym)
Nucleocapsid protein,NP,Protein N
表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
SARS-CoV-2 Nucleocapsid protein, His Tag (NUN-C5227) is expressed and secreted by human 293 cells (HEK293). It contains AA Met 1 - Ala 419 (Accession # QHO62115.1).
Predicted N-terminus: Met 1
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus
The protein has a calculated MW of 47.3 kDa. The protein migrates as 60-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
Nucleocapsid (N) 蛋白是冠狀病毒中發(fā)現(xiàn)的最豐富的蛋白質(zhì)。冠狀病毒N蛋白是一種高度免疫原性的磷蛋白,對(duì)病毒基因組復(fù)制和細(xì)胞信號(hào)通路的調(diào)節(jié)很重要。它是由一個(gè)研究小組在冠狀病毒(CoV)感染期間篩查ADP核糖基化蛋白時(shí)首次發(fā)現(xiàn)的(Grunewald M.E.等人,2017,病毒學(xué);517:62-68)。N蛋白中包含的多種功能活性使其不僅是一種結(jié)構(gòu)蛋白,也是抗病毒治療開發(fā)中的一個(gè)有趣靶點(diǎn)。由于N蛋白序列的保守性及其強(qiáng)免疫原性,冠狀病毒的N蛋白被選為診斷工具。
