Anti-SARS-CoV-2 Spike Glycopro

Cayman的抗SARS-CoV-2刺突糖蛋白RBD IgG ELISA试剂盒是一种酶联免疫吸附测定法，可用于定性评估人血浆和血清中是否存在针对SARS-CoV-2刺突糖蛋白RBD的抗体。一般来说，虽然PCR阳性表明存在病毒抗原，但这种血清学检测表明存在针对SARS-CoV-2刺突糖蛋白RBD的IgG抗体，这种情况发生在SARS-CoV-2感染后的几周内。该试剂盒中测量的IgG反应无法区分中和抗体（专门中断刺突糖蛋白RBD与宿主细胞上的ACE2受体之间的相互作用）与与RBD结合的非中和抗体。该试剂盒中包含阳性对照，以提供血清阳性的截止值。Cayman's Anti-SARS-CoV-2 Spike Glycoprotein RBD IgG ELISA Kit is an enzyme-linked immunosorbent assay that can be used for the qualitative assessment of the presence of antibodies against the SARS-CoV-2 spike glycoprotein RBD in human plasma and serum. In general, while PCR positivity indicates the presence of viral antigens, this serological assay indicates the presence of IgG antibodies against the SARS-CoV-2 spike glycoprotein RBD, which occurs in the weeks following SARS-CoV-2 infection. The IgG response measured in this kit does not differentiate neutralizing antibodies, which specifically interrupt the interaction between the spike glycoprotein RBD and the ACE2 receptor on the host cell, from non-neutralizing antibodies that bind to the RBD. A positive control is included in this kit to provide a cut-off for seropositivity.分子式分子量
