This ELISA kit was used for quantification of IFN-gamma in the supernatants of SEB-stimulated peripheral blood mononuclear cells in combination with conventional chemotherapeutics. The variability of the technical replicates was low and the data obtained very repetitive.

KYNAN Pharma
This human IFNg ELISA kit works very well. Steps included in the manufacturer's protocol were easy to follow and all the necessary materials were provided. The snap wells come in handy when running multiple experiments in small batches for optimization of the sample. We ran human plasma samples and the standards ran evenly and the detection concentration fell within the provided range which is rare for quantifying IFNg levels in human samples.

This is the first time I've run an Interferon-g ELISA and I'm very happy with the results. I typically use the ELISpot platform and I'm happy that the results with this kit are far superior- very little background and fairly sensitive with the detection. I may try the newer version (with the qRT-PCR) readout for subsequent experiments to compare between kits.

Mayo Clinic
This human IFNg ELISA kit is good. Steps were clear and all necessary materials were provided. Since we ran multiple smaller experiments, snap wells were really handy. We used BAL from mice lungs and though the standard ran evenly, samples showed low IFNg levels.

University of Pittsburgh
The human IFNg ELISA kit is easy to follow and reproducible. We used the kit with IFNg-secreting human cell lines following the manufacturer's protocol after the cells were treated with LPS. The supernatant was used to detect the IFNg. The kit worked perfectly when detecting high content of IFNg. However, when the IFNg content is low in the samples, more repeats may be needed as the sensitivity or accuracy of the kit is becoming low, too. Overall, the kit works well in detecting IFNg.
