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. In addition to having antiviral activity, IFN-gamma has important immunoregulatory functions. IFN-gamma plays an important role in the control of neointima proliferation.

Recommended Sample Dilution Ratios
According to our internal validation assays using this ELISA kit, to detect IFN-gamma, Dilution ratio of 1:1, concentration in serum is less than the lowest standard, 31.2 pg/ml..
Some articles we found to cite concentrations of IFN-gamma in samples: 25380621 (Pubmed IDs).
Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Rat IFN Gamma/IFNG/Interferon Gamma ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring IFN-gamma using the EK0374 Rat IFN-gamma Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2019-07-30
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may affect the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to limit protein degradation.

Question
Q: can you suggest the dilution ratio of serum samples for detection of IFN-gamma in Rat serum? I am trying to measure a multiple analytes and it requires 100ul of diluted samples for each well. We have limited sample quantitys so we like to dilute as much as possible.
S. Davis
Verified customer
Asked: 2014-10-28
Answer
A: without knowing the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the IFN-gamma ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: if the enzyme conjugated IFN-gamma antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the IFN-gamma antigen?
Verified Customer
Verified customer
Asked: 2014-03-16
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.
