简介
Nucleoprotein/NP Protein is essential for viral replication and transcription. Nucleoprotein/NP Protein binds to viral RNA to form a ribonucleoprotein complex required for genome replication. Nucleoprotein/NP Protein promotes NLRP3 inflammasome activation to induce excessive inflammation. SARS-CoV-2 Nucleocapsid Protein (Omicron, B.1.1.529, His) is the recombinant Virus-derived SARS-CoV-2 Nucleocapsid protein, expressed by E. coli , with N-His labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Protein Description
The SARS-CoV-2 nucleocapsid (N) protein plays a crucial role in the viral life cycle, being essential for RNA encapsidation, genome packaging, and viral assembly. As one of the most abundant proteins in the virus, the N protein is a key target for diagnostic assays and vaccine development. Research into the N protein has accelerated due to the COVID-19 pandemic, as it is highly immunogenic and elicits strong antibody responses in infected individuals. Understanding the structure and function of the N protein is vital for the design of effective therapeutics and vaccines. Moreover, recombinant N proteins are being utilized in serological tests to detect antibodies against SARS-CoV-2, aiding in surveillance efforts and epidemiological studies. The ongoing studies focus on characterizing the N protein's interactions with other viral components and host cell factors, as well as its potential as a biomarker for disease progression. Overall, the investigation of SARS-CoV-2 nucleocapsid recombinants underscores their significance in combatting the ongoing pandemic and provides insights for future coronavirus-related research.
