Human STAT3 ELISA Kit

This assay has high sensitivity and excellent specificity for detecting Human STAT3 (Signal Transducer And Activator Of Transcription 3). The assay range is from 0.156 to 10 ng/ml (Sandwich kit) with a sensitivity of 0.062 ng/ml. There is no detectable cross-reactivity with other relevant proteins. Activity loss rate and accelerated stability test ect have been conducted to guarantee the best performance of the products after long storage and delivery.

• High sensitivity and specificity
• Perfect reproducibility and consistency across batches
• Quality control with three-level inspections
• Wide range of targets/species available
• Intra-assay: CV<10%; Inter-assay: CV<12%

STAT3, a transcription factor for acute phase response genes, acts as an adaptor molecule in signal transduction from the type I interferon receptor. They found that it binds to a conserved sequence in the cytoplasmic tail of the IFNAR1 chain of the receptor and undergoes interferon-dependent tyrosine phosphorylation. The p85 regulatory subunit of phosphatidylinositol 3-kinase, which activates a series of serine kinases, was found to bind to phosphorylated STAT3 and subsequently to undergo tyrosine phosphorylation. The authors concluded that STAT3 acts as an adaptor to couple another signaling pathway to the interferon receptor.In many human cancers and transformed cell lines, STAT3 is persistently activated, and in cell culture, active STAT3 is either required for transformation, enhances transformation, or blocks apoptosis.
