Description :Rabbit Polyclonal Antibody
Specificity :Recognizes the STAT4 protein
Cited Applications :WB
Cross Reactivity :Western blot of human STAT4
STAT4 from other species may also be detectable.
Immunogen :Synthetic peptide corresponding to amino acids 691-695 of human STAT4
Purification :Affinity chromatography
Stability :Store at 4°C (add 0.1% NaN3) for several months, and at -20°C for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
Sample Data :Representative western blot with Anti-STAT4 (1:1000) using 20 ng of human recombinant STAT1β, STAT2, STAT3, STAT4, STAT5, and STAT6.
Scientific Background :STAT4 (signal transducer and activator of transcription 4) is a member of the STAT family that is phosphorylated by receptor-associated protein kinases. STATs form homo- or heterodimers and translocate to the cell nucleus where they act as transcription activators. T helper (Th) cells differentiation is regulated by STAT4 (1). STAT4 controls T1/T2 balance during the response to live influenza virus and isolated viral proteins. The differentiation of gamma interferon (IFN-γ)-producing Th1 and Tc1 cells after inoculation of live virus occurred independently of STAT4 expression. STAT4 has been shown to control pathogenesis of chronic obstructive pulmonary disease (2).
