Product specifications

Intended use

This ELISpot Path kit is intended for the enumeration of cells secreting human IFN-γ in response to TB peptides using the ELISpot assay. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

Peptide pool composition
The scanning pools consist of synthetic peptides of 15-mers overlapping with 11 amino acids, covering the complete proteins. The ESAT-6 scanning pool is derived from the early secretory antigenic target protein and contains 21 peptides. The CFP-10 scanning pool is derived from the culture filtrate protein and contains 23 peptides. Finally, the EspC scanning pool is derived from the ESX-1 secretion-associated protein and contains 23 peptides.

Shipping and Storage

Shipping

Shipped at ambient temperature.

Storage

Store antibodies, enzyme conjugate, and substrate at 4-8 °C. Peptide pools should be stored at -20 °C or below. Plates may be kept at room temperature.

Shelf lifeAt least 18 months from date of receipt.
PBMC (250,000 cells/well) from an individual with latent tuberculosis were incubated overnight in the absence or presence of the ESAT-6, CFP-10, and EspC scanning pools (Mabtech) and the number of cells secreting IFN-γ was analyzed by ELISpot.

IFN-γ

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. Thus, high-level production of IFN-γ is typically associated with effective host defense against intracellular pathogens.
