Editor's Notes
- #2: Does your next experiment involve IFN gamma? This video is for scientists who want to run Western blot, IHC, flow or other immunoassays against IFN gamma.
- #3: We will cover some basic facts, protein expression, and IFN gamma’s expected behavior in Western blot. All information in this video is based on public information and no proprietary experimental evidence was used.
- #4: Topic 1: Quick facts about IFN gamma. Interferon gamma is part of the cytokine family of secreted proteins produced by immune cells such as natural killer cells and T helper type 1 cells. It is heavily involved in the activation of antimicrobial, antiviral, and antitumor immune responses. While IFN gamma has some structural differences across vertebrates, its structure and function remain largely conserved. The precursor of IFN gamma is 166 amino acids long while the mature form is 138 amino acids long and runs about 23 kilodaltons on Western blot.
- #5: Topic 2: Where is IFN gamma expressed? High RNA expression levels of IFN gamma have been found in the organs involved in immune cell production or immune response. It is expressed at a high level in the appendix and lymph nodes. However, the highest levels of IFN gamma are found in the bone marrow. Lungs, liver, and urinary bladder also express a considerable amount of IFN gamma. You can find more information at protein atlas dot org including which cell lines express IFN gamma and which ones don’t. This information will come in handy when designing positive and negative controls for western blot and immunohistochemistry.
- #6: Topic 3: IFN gamma in Western blotting. Antibody specificity can make or break an experiment. After looking through Western blot images from publications and antibody companies, we can see that typically one band can be expected in an IFN gamma Western blot from around 17 to 25 kilodaltons as a result of differential glycosylation. Check out the PMC link for more images, which is also provided in the description box.
- #7: Topic 4: Some interesting facts about Interferon gamma. IFN gamma has been shown to promote anti-cancer activity in vitro. This usually happens through the induction of apoptosis, but autophagy has been reported as another observed mechanism. Interestingly, IFN gamma is also involved with the thinning of decidual arterial walls to enhance blood flow to the embryo implantation site, which helps with placental development.
