The three-step bridging Gyrolab SARS-CoV-2 antibody immunoassay utilizes a Gyrolab Bioaffy™ CD. The method encompasses a biotinylated SARS-CoV-2, Spike RBD-His recombinant protein as the capture molecule, and SARS‑CoV-2 Spike RBD-Fc recombinant protein labeled with Alexa Fluor® 647 as the detection molecule. This assay detects IgG, IgA and IgM antibody subtypes within the human serum.
3. 分析范围 Gyrolab SARS-CoV-2的抗体免疫分析技术检测动态范围为40 ng/mL——200μg/mL。可切换不同型号的CD,优化后获得更宽检测范围。 Average responses obtained for a negative control (NC) and positive controls ranging from 40 ng/mL to 200 µg/mL (in neat serum) in Rexxip H containing 25% human serum. Rabbit polyclonal anti-SARS-CoV-2 Spike RBD antibody was used as positive control.
2. Gyrolab在疫苗开发中的应用 疫苗开发过程中的生物分析在分析复杂性、样品基质、分析物类型的多样性以及对工作流程效率的要求等方面提出了许多挑战。由于COVID-19疫苗开发的项目时间表经常被压缩以缩短开发时间,从而达到抗击流行病的目的,因此对快速生成数据的需求也越来越大。Gyrolab平台因为消除了手动ELISA长时间孵化时间,能够更大限度地提高免疫分析速度。 Customer example of improvements in analysis time, dynamic range, sample savings, and assay development time when transitioning from ELISA to Gyrolab immunoassay.
Gyrolab平台免疫分析用于疫苗开发,以表征疫苗的滴度、纯度、亲和力和效力,以及它们在动物和人类中的免疫原性反应。Gyrolab分析灵活性允许在单个Gyrolab Bioaffy CD上运行多个分析,如下例所示。 Immunogenicity responses in a preclinical mouse study detecting IgG antibody subtypes simultaneously in a single run were analyzed with Gyrolab immunoassays to screen responses from different formulations.
