产品描述：
Coronaviruses are commonly comprised of four structural proteins: Spike protein (S), Envelope protein (E), Membrane protein (M) and Nucleocapsid protein (N) . The SARS-CoV-2 S protein is a glycoprotein that mediates membrane fusion and viral entry. The S protein is homotrimeric, with each ~180-kDa monomer consisting of two subunits, S1 and S2 . The RBD of SARS-CoV-2 binds a metallopeptidase, angiotensin-converting enzyme 2 (ACE-2). First detected in India in December 2020, the B.1.617.2, or Delta variant, is considered a Variant of Concern (VOC) as it contains several mutations in the RBD domain that potentially affect viral fitness and transmissibility: L452R and T478K.

| 产品别称 | S protein RBD; S glycoprotein RBD; Spike protein RBD |
| 种属 | SARS-COV-2 |
| 表达序列 | Arg319-Phe541(L452R, T478K) |
| Accession | P₀DTC₂ |
| 标签 | His tag at the C-terminal |
| 表达系统 | HEK293 Cells |
| 分子量 | Approximately 26.26 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result. |
| 纯度 | > 95% as determined by SDS-PAGE and HPLC. |
| 内毒素 | < 1.0 EU per 1μg of the protein by the LAL method. |
| 制剂 | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |

文献和实验日前，北京大学生命科学学院魏文胜课题组在 Cell 杂志上在线发表题为“Circular RNA Vaccines against SARS-CoV-2 and Emerging Variants”的研究论文。 魏文胜团队首先建立了体外高效制备高纯度环状 RNA 的技术平台，针对新型冠状病毒及其变异株，设计了编码新冠病毒刺突蛋白（Spike）受体结构域（RBD）的环状 RNA 疫苗。 该项研究中制备的针对新冠病毒德尔塔变异株的环状 RNA 疫苗（circRNARBD
XBB.1.5 毒株的传播力为何这么强？北大曹云龙团队最新研究揭示相关机制
导读 SARS-CoV-2 变体 BQ.1.1 和 XBB.1 已在全球范围内传播，前期的研究数据表明，这两个变体与大多数 Omicron 突变体相比具有更优越的生长优势。但是，根据最新的消息，另一 SARS-CoV-2 重组亚型 XBB.1.5 在美国感染人数快速增长，已迅速成为美国的优势毒株，预计很快将会超过现有的流行亚型，并且极有可能引发下一波全球 COVID-19 传播。 图片来源：bioRxiv 尽管 XBB.1.5 拥有着高传播性，但是其内在的分子机制目前仍不清楚。2023 年
