Scientific Data

Immunoprecipitation Immunoprecipitation of Human STAT4. View Larger

Immunoprecipitation of Human STAT4. STAT4 was immunoprecipitated from lysates (1 x 106- 107cells) of human peripheral blood lymphocytes (PBL) following incubation with 3 µg Human/Mouse STAT4 Polyclonal Antibody (Catalog # PA-ST4) for 1 hour at 2 - 8 ºC. STAT4-antibody complexes were absorbed using Protein A Immunoprecipitin (Life Technologies). Immunoprecipitated STAT4 was detected by Western blot using a 1:2000 dilution of Human/Mouse STAT4 Polyclonal Antibody (Catalog # PA-ST4).

Background: STAT4

Signal transduction and activator of transcription 4 (STAT4) is a member of the Jak/STAT signal transduction pathway. STAT4 mediates cytokine signaling by acting as a signal transducer in the cytoplasm and, upon phosphorylation, homo or heterodimerizes with other STAT proteins, which then translocate to the nucleus and activate transcription of specific genes. STAT4 is expressed in subset of tissues including spleen, heart, brain, peripheral blood cells and testis. STAT4 is involved in mediating IL-12 response in lymphocytes and regulating T helper cell differentiation.
