产品描述： 产品名称：2019 nCOV Spike RBD Protein 背景说明: The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. 英文别名: S protein RBD,Spike glycoprotein Receptor-binding domain,S glycoprotein RBD,Spike protein RBD Accession: QHD43416.1 中文别名: 2019 nCOV Spike RBD蛋白 序列: Arg319-Asn532 标签: C-mFc 种属: SARS-CoV-2 来源: Recombinant 2019 nCOV Spike RBD Protein is expressed from Expi293 with mFc at the C-terminal.;It contains Arg319-Asn532. 分子量: The protein has a predicted MW of 49.7kDa.Due to glycosylation, the protein migrates to 60-70 KDabased on Bis-Tris PAGE result. 纯度: > 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC 内毒素水平: Less than 1 EU per μg by the LAL method. 形态: Lyophilized from 0.22um filtered solution in PBS (pH 7.4).Normally 5 % trehalose is added as protectant before lyophilization. 储存/保存方法: The product should be stored at -70℃ or -20℃.

文献和实验Expression of Recombinant Cytochromes c in E. coli
for proper folding and stability. However, significant advances in expression of recombinant cytochromes c have been made during the last decade. It has been shown that a single gene cluster, ccmA–H , is responsible for cytochrome c maturation in Escherichia
. This purification process resulted in greater than 95% pure rBoNTC(Hc )-C based on SDS-PAGE, and yielded up to 0.2 g of rBoNTC(Hc )-C/kg cells. The final protein yield is a function of protein expression level during fermentation and the purification methods
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
