Triple Breakthrough in IFN-γ ELISA Kits: Higher Sensitivity, Faster Speed, and Broader Linearity

Interferon - γ (IFN - γ) is the sole member of the type II interferon family. It is a pro - inflammatory cytokine mainly secreted by activated T cells (such as Th1, CTL) and natural killer (NK) cells. Its molecular structure is a biologically active homodimer. It activates the JAK - STAT signaling pathway by binding to IFNGR1/IFNGR2 receptors to regulate the expression of downstream genes. As a core regulator of the immune system, IFN - γ has a broad - spectrum antiviral function. It inhibits viral replication by inducing interferon - stimulated genes such as Mx protein and protein kinase R, and enhances the expression of MHC - I/II molecules to promote antigen presentation. In immune regulation, it drives Th1 - type immune responses, activates the tumor - killing function of macrophages, and at the same time recruits immune cells to the tumor microenvironment through the secretion of CXCL9/10/11 chemokines to play an anti - tumor role. Clinical detection of IFN - γ is of great value for the diagnosis of infectious diseases and the evaluation of the efficacy of tumor immunotherapy.

Innovative Advancement! Starter Bio proudly introduces three groundbreaking one-step IFN-γ ELISA kits, meticulously designed to meet diverse experimental needs with unparalleled precision.

Human IFN - γ OneStep ELISA Kit: Hypersensitive Residual Detection

With a sensitivity of 3.4 pg/ml and a detection range of 3.4 - 217 pg/ml, it has been calibrated and verified by the NIBSC international standard. It can precisely capture trace samples, making it the first choice for residual detection! The experiment only takes 1 hour!

Human IFN - γ Broad range ELISA Kit: Wide - range Coverage

The linear range is 0.8 - 1739 pg/ml. One kit can handle samples with widely different concentrations, eliminating the trouble of dilution!

Human IFN - γ OneStep OptiQuant ELISA Kit: OptiQuant Range Competing with Big - name Products, Faster, More Accurate

The detection range is 15 - 1000 pg/ml. The experiment can be completed in 45 minutes, enabling efficient and rapid detection without waiting!
