Comprehensive Assessment of Immune Response
When a pathogen infects the body, it initiates a cascade of complex immune reactions involving innate and adaptive arms of the immune system. Understanding these immune responses to infection provides greater insight as to why some individuals are more vulnerable to infection and related complications than others.As COVID-19 has shown us, we need to gain deeper knowledge into the complex interplay between different elements of the immune system for rapid development of novel vaccine and therapeutic approaches.싸토리우스’ advanced cell and protein analysis platforms accelerate discovery and development of new vaccines against viral infections by providing comprehensive, more relevant data on key immune responses such as:

Identifies and measures the affinity and kinetics of neutralizing antibodies to viral proteins.The iQue® SARS-CoV-2 (IgG, IgM and IgA) Kit is a bead-based immunoassay designed for simultaneous detection of human IgG, IgM and IgA antibodies specific for SARS-CoV-2 Spike protein RBD produced by the immune system in response to viral infection or vaccination.Figure 1: iQue® SARS-CoV-2 (IgG, IgM and IgA) Kit workflow. Easy to follow steps and low sample volumes needed (requires only a single 10 µL of plasma / serum diluted at least 100-fold).

Epitope binning assays help identify antibodies that block the same epitope on a target antigen and are crucial when it comes to identifying or engineering mAbs with favorable kinetics and affinity profiles. This assay format can also be used to determine neutralization antibody competition with virus receptor binding to host receptors.Explore More
Real-time Kinetics (association and dissociation) and affinity data allows to confidently pick target binding lead candidates fast. Binding activity measurements can also be used to determine protein stability and activity, especially useful in vaccine antigen selection.Explore More

The automated iQue® High-Throughput 선별 (HTS) by Cytometry Platform allows scientists to rapidly multiplex protein analysis, immunophenotyping and perform functional assessments. It offers ready-to-use kits including the iQue® T Cell Phenotyping kit, Human Qbeads® Inflammation Panel for 사이토카인 storm assessment, and kits for T cell activation, memory, killing, and 탈진 along with 사이토카인 profiling for greater in-depth characterization of the host immune response in each sample.
Octet® BLI systems offer a rapid and effective method for protein quantitation due to their enhanced throughput, decreased sample preparation requirements, and low cost of operation. Samples run on Octet® systems are also recoverable, so that researchers may save and reuse precious sample for other experiments. In addition, Octet® assays are not affected by absorption interferences in colored samples or by light scattering with turbid samples, enabling measurement of analyte concentration in crude matrices such as cell culture supernatant, cell lysate and serum.
The iQue® HTS Platform, as well as the Octet® BLI systems have been widely used for measurement and characterization of humoral immune responses i.e. 선별 for antibody binding to SARS-CoV-2 proteins of COVID-19 patients.Dogan, M., Kozhaya, L., Placek, L., Gunter, C., Yigit, M., Hardy, R., Plassmeyer, M., Coatney, P., Lillard, K., Bukhari, Z., Kleinberg, M., Hayes, C.,- Arditi, M., Klapper, E., Merin, N., Liang, B.T., Gupta, R., Alpan, O., & Unutmaz, D.
