蛋白构建A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike S1 (YP_009724390.1, with mutations L18F, D80A, D215G, LAL242-244 deletion, R246I, K417N, E484K, N501Y, D614G) (Met1-Arg685) was expressed with a polyhistidine tag at the C-terminus. The mutations were identified in the SARS-CoV-2 variant (known as 20C/501Y.V2 or B.1.351 lineage) which emerged in South Africa.

分子量The recombinant SARS-CoV-2 (2019-nCoV) Spike S1 consists of 678 amino acids and predicts a molecular mass of 76 kDa. As a result of glycosylation, it migrates as an approximately 106.3 kDa band in SDS-PAGE under reducing conditions.
缓冲液Lyophilized from sterile PBS, pH 7.4.
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件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.
复溶A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

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

IS为 Initial segment之缩写。系指神经元的尖峰脉冲中由轴突始端（ Initial segment）兴奋所引起者。所谓轴突始端，即细胞体向轴突之移动部分，在有髓神经来说，亦即轴突还未覆盖髓鞘的部分。因许多神经元的轴突起始端之阈值比细胞体或树突低，所以由兴奋性突触后动作电位而产生 IS尖峰脉冲。
