Background SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Nucleocapsid Protein is associated with nucleic acid. It is the most abundant protein for coronavirus. Coronaviruses are enveloped viruses with a positive-sense RNA genome and with a nucleocapsid of helical symmetry. Coronavirus nucleoproteins localize to the cytoplasm and the nucleolus, a subnuclear structure, in both virus-infected primary cells and in cells transfected with plasmids that express N protein. Coronavirus N protein is required for coronavirus RNA synthesis, and has RNA chaperone activity that may be involved in template switch. Nucleocapsid protein is a most abundant protein of coronavirus. During virion assembly, N protein binds to viral RNA and leads to formation of the helical nucleocapsid. Nucleocapsid protein is a highly immunogenic phosphoprotein also implicated in viral genome replication and in modulating cell signaling pathways. Because of the strong immunogenicity of coronavirus Nucleocapsid, it is believed that SARS-CoV-2 Nucleocapsid Protein has potential value for the diagnosis of the virus.

Figure 1. The antibody stability at room temperature was determined by functional ELISA. Immobilized 2019-nCoV Nucleocapsid Protein (新型冠状病毒N蛋白) (P2328) at 100ng/well can bind SARS-CoV-2 N Protein Human Monoclonal Antibody (Clone B2). After storing at room-temperature for 1 week, 2 weeks or 4 weeks, the EC50 of this antibody showed no significant change.

Figure 2. The repeated freeze-thaw (FT) stability of antibody was determined by functional ELISA. Immobilized 2019-nCoV Nucleocapsid Protein (新型冠状病毒N蛋白) (P2328) at 100ng/well can bind SARS-CoV-2 N Protein Human Monoclonal Antibody (Clone B2). After 10 freeze-thaw cycles, the EC50 of this antibody showed no significant change.

Figure 3. Immobilized 2019-nCoV Nucleocapsid Protein (新型冠状病毒N蛋白) (P2328) at 100ng/well can bind SARS-CoV-2 N Protein Human Monoclonal Antibody (Clone B2), and the EC50 is less than 0.21μg/ml.

保存条件:

SARS-CoV-2 N Protein Human Monoclonal Antibody (Clone B2) 4℃保存,至少一年有效。短期内不使用,推荐-20℃保存,-20℃可以保存更长时间。

注意事项:

如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验,请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体,包括已经使用过的稀释抗体,请4℃保存。

回收后重复使用的抗体,使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象,可以10,000×g离心1-3分钟,取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况,则可以考虑废弃该抗体。

本产品仅限于专业人员的科学研究用,不得用于临床诊断或治疗,不得用于食品或药品,不得存放于普通住宅内。

为了您的安全和健康,请穿实验服并戴一次性手套操作。

请根据抗体的实际用途选择相应的使用方法。
1.Western检测:
a.按照推荐的稀释比例用碧云天提供的Western一抗稀释液稀释抗体。
b.把经过封闭的蛋白膜与稀释好的一抗4℃缓慢摇动过夜或室温缓慢摇动2小时,确保稀释的抗体至少能在摇动的瞬间覆盖蛋白膜。
c.回收稀释的一抗,4℃保存以备下次继续使用。
d.按照Western的实验步骤进行后续的洗涤、二抗孵育、洗涤和检测等操作。具体操作可以参考如下网页:
