• Gene Name:

  Signal transducer and activator of transcription 2

• Gene Aliases:

  IMD44; interferon alpha induced transcriptional activator; ISGF-3; P113; PTORCH3; signal transducer and activator of transcription 2; signal transducer and activator of transcription 2, 113kDa; STAT113.

• Gene ID:

  6773

• Accession Number:

  NP_005410

• Reactivity:

  Homo sapiens|Human

• Target:

  Signal transducer and activator of transcription that mediates signaling by type I IFNs (IFN-alpha and IFN-beta) . Following type I IFN binding to cell surface receptors, Jak kinases (TYK2 and JAK1) are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, associate with IRF9/ISGF3G to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes, which drive the cell in an antiviral state (PubMed:9020188, PubMed:23391734) . Acts as a regulator of mitochondrial fission by modulating the phosphorylation of DNM1L at 'Ser-616' and 'Ser-637' which activate and inactivate the GTPase activity of DNM1L respectively (PubMed:26122121) .

• Type:

  ELISA Kit

• Applications:

  Enzyme-linked Immunosorbent assay-Sandwich

• Detection Method:

  Colorimetric

• Assay Principle:

  The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Signal Transducer And Activator Of Transcription 2 (STAT2) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Signal Transducer And Activator Of Transcription 2 (STAT2) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Signal Transducer And Activator Of Transcription 2 (STAT2), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Signal Transducer And Activator Of Transcription 2 (STAT2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
