Validation Data Gallery

• 

  Purity of recombinant human IFN gamma was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue

• 

  Recombinant human IFN gamma (HZ-1301) dose-dependently inhibits proliferation of the HT-29 human colorectal adenocarcinoma cell line. Cell number was quantitatively assessed by PrestoBlue® cell viability reagent. HT-29 cells were treated with increasing concentrations of recombinant IFN gamma for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model.The EC50 range is 0.02-0.14 ng/mL.

Background

Interferon gamma (IFN γ), is a type II interferon that provides immunity against bacterial, viral and protozoan infections. In its active form, IFN γ is a glycosylated, non-covalently linked homodimer of 17, 21-32 kDa subunits. It is produced by a number of immune cell types including natural killer cells, natural killer T cells, and effector lymphocyte T cells following antigenic and inflammatory triggers. The IFN γ dimer binds to its cognate receptor which has two subunits: IFN-γR1 which is the ligand-binding chain (α chain) and IFN-γR2, the signal-transducing chain (β chain). Binding to the receptor activates the JAK/STAT pathway which in turn activates IFN γ responsive genes. While IFN γ can inhibit viral replication, it also works as an immune-modulator and immune-stimulator by increasing surface expression of class I MHC proteins (PMID: 19268625; 10688427)

I have used this cytokine to induce and activate THP-1 derived macrophages and human MDM to check the immune response of macrophages against Mtb. We observed a good immune primed response from the marophages and it helped to get a good results. specially when we tested Mtb mutant strain to subvert host immune response and this cytokine kind of served as a control to study the immune response.

• Applications: Cell culture
• Cell Tissue Type: THP-1 and MDM
