- 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
Method :Sandwich ELISA
Species :Bovine, ovine and caprine
Specimens :Activated plasma or culture supernatant
Coated antigen :Anti-ruminant IFN-g monoclonal antibody
Conjugate :Anti-ruminant IFN-g HRP Mab conjugate
