PepPool: SARS‑CoV‑2 (S1), scanning

Human PBMC (300,000 cells/well) from a convalescent individual, previously confirmed CODID-19 positive with PCR, were incubated overnight in the absence or presence of the SARS-CoV-2 S1 scanning pool and anti-CD28 mAb and the number of cells secreting IFN-γ was analyzed by ELISpot.
Human PBMC from three COVID-19 convalescent individuals, previously confirmed SARS-CoV-2 positive with PCR, and PBMC from one individual collected before the SARS-CoV-2 pandemic were incubated overnight in the absence or presence of the SARS-CoV-2 S1 scanning pool and anti-CD28 mAb. The number of cells secreting IFN-γ, IL-2 and both analytes was analyzed by FluoroSpot using Mabtech IRIS.

Product specifications

Intended use

This peptide pool is intended for studying immune responses against SARS-CoV-2 (S1 domain of spike protein) using immunoassays such as ELISpot and FluoroSpot. It induces cytokine secretion from antigen-specific human T cells. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

Description
The SARS-CoV-2 (S1) scanning pool induces secretion of e.g., IFN-γ, IL-2, and granzyme B from human T cells. It contains 166 peptides from the human SARS-CoV-2 virus. The peptides are 15-mers overlapping with 11 amino acids, covering the S1 domain of the spike protein (amino acid 13-685). The pool is supplied in two vials: pool 1 SARS-CoV-2 S1 peptides 1-83 (83 peptides) and pool 2 SARS-CoV-2 S1 peptides 84-166 (83 peptides). The mean purity of the synthetic peptides is 80%.

Peptides included in the peptide pool are listed in the datasheet.
