Background of IFN-gamma

Interferon-gamma (IFN-gamma) is an inflammatory cytokine that has been implicated in the development of fibrosis in inflamed tissues. The production of IFN-gamma, which is under genetic control, can influence the development of fibrosis in lung allografts. IFN-gamma is also produced by natural killer (NK) cells and most prominently by CD8 cytotoxic T cells, and is vital for the control of microbial pathogens. Interferon gamma is believed to be crucial for host defence against many infections. Genetically determined variability in IFN-gamma and expression might be important for the development of tuberculosis. IFN-gamma activates human macrophage oxidative metabolism and antimicrobial activity. In addition to having antiviral activity, IFN-gamma has important immunoregulatory functions. IFN-gamma plays an important role in the control of neointima proliferation.

1 Reviews For Human IFN Gamma/IFNG/Interferon Gamma ELISA Kit PicoKine®


Very Easy To Work With And Great Results With Least Standard Error--Akshay Jain, University of Missouri, Kansas City, Pharmaceutical Sciences, Research Assistant



Applications ELISA (Inflammatory cytokine assay from plasma)
Sample Rat plasma
Detection --

"I used this assay kit for detection of the cytokines in the plasma samples. Only 100 uL of sample yielded absolutely flawless results. Plasma samples showed variable cytokine expression among independent groups which demonstrates the accuracy of this kit. Straightforward protocol. Very easy to perform. Highly recommended product for precise cytokine assay analysis." (Customer’s Tip: "Keep working area clean. Prepare necessary dilution of the sample before starting the procedure.")

8 Customer Q&As for Human IFN Gamma/IFNG/Interferon Gamma ELISA Kit PicoKine®


Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis IFN-gamma using the EK0373 Human IFN-gamma Picokine® ELISA Kit?

M. Liu

Verified customer

Asked: 2020-11-24


A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may alter the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples to limit protein degradation.

Is EK0373 suitable for co-culture Target Cells and Effector Cells and ELISA with cell culture fluid?

Verified customer

Asked: 2020-11-12


Our lab hasn't worked on co-culture cell samples using the Human IFN Gamma ELISA Kit PicoKine™ (EK0373). Please run a pilot test to see if the kits could work on the specific samples.

Q: which procedure should I follow in order to thaw whole blood sample for IFN-gamma ELISA after freezing?

Y. Sunder

Verified customer

Asked: 2020-01-03


A: do not freeze and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test IFN-gamma for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Asked: 2018-02-18


A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Q: Can IFN-gamma ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

T. Taylor

Verified customer

Asked: 2016-09-03


A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is a must. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been assessd by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please check the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Dear Support: I purchased your product EK0373, can the reconstituted standard at 25pg/ml be stored at 2-8C until the expiration and be reused? Can the PBS substituted with PBST as the wash buffer?

Verified Customer

Verified customer

Asked: 2014-06-19


We do not recommend storing reconstituted standard for these EK0373 antibody because it is not stable and it may not work after storage. Yes, the wash buffer can be substituted with PBS with 0.05% Tween.
