Paves your way to functional analysis of a specific research question.
Intended use
This FluoroSpot Path kit is intended for the enumeration of cells secreting human IFN-γ and IL-2 in response to SARS-CoV-2 (S+NMO) peptides using the FluoroSpot assay. For research use only. Not for use in diagnostic procedures.
Peptide pool composition
The SARS-CoV-2 S defined peptide pool contains 100 peptides from the human SARS-CoV-2 virus. The peptides are derived from the spike (S) protein.
The SARS-CoV-2 NMO defined peptide pool contains 101 peptides from the human SARS-CoV-2 virus. The peptides are derived from the nucleoprotein (N), membrane protein (M), and open reading frame (ORF) proteins (O): ORF1, nsp3, ORF-3a, ORF-7a, and ORF8.
Performance
Human PBMC (250,000 cells/well) from one COVID-19 vaccinated individual (mRNA vaccine with spike sequence), one COVID-19 convalescent individual, and from one individual collected before the SARS-CoV-2 pandemic were incubated overnight in the absence or presence of the SARS-CoV-2 S defined peptide pool, SARS-CoV-2 NMO defined peptide pool in the presence of anti-CD28 mAb. The number of cells secreting IFN-γ, IL-2 and both analytes was analyzed by FluoroSpot using Mabtech IRIS.
Analyte description -
Interferon-γ (IFN-γ) is the only type II interferon. This proinflammatory cytokine is secreted by activated T cells and NK cells. It activates macrophages and endothelial cells and regulates immune responses by affecting APCs, T cells, and B cells. Production of IFN-γ by helper T cells and cytotoxic T cells is a hallmark of the Th1-type phenotype.
