ID Screen® Ruminant IFN-g

IDvet offers a complete solution for Bovine TB diagnosis via the IGRA method, including avian and bovine PPD tuberculin antigens and the ID Screen® Ruminant IFN-g sandwich ELISA. Download our product brochure.

Sandwich ELISA for the detection of ovine, bovine and caprine interferon gamma (IFN-g) in activated plasma or culture supernatant.

  • Standardized results thanks to a freeze-dried positive reference control used to calculate S/P ratios for each sample
  • Flexible: the same kit may be used with both native antigens (standard protocol) and recombinant / peptide antigens (alternative protocol)
  • Practical: the standard protocol uses only 10μl per sample, meaning that less sample volume is required for cell activation
