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.


Product details

ProductELISpot Path: TB (ESAT-6+CFP-10+EspC) Human IFN-γ

This kit is based on a matched pair of mAbs specific for human IFN-γ.

Shipping and Storage


Shipped at ambient temperature.


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.

Tuberculosis diagnosis with spots
Early and precise diagnosis is crucial for effective TB management, and ELISpot is increasingly being used for this purpose. This white paper examines the advantages of ELISpot in TB diagnosis and suggests future antigens and biomarkers that can enhance diagnostic accuracy.

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.
