Using a STAT3 antibody in chromatin immunoprecipitation (ChIP)

Signal transducer and activator of transcription 3 (STAT3) is an important oncogenic transcriptional factor that mediates tumor induced immune suppression.  Specifically, STAT3 transmits signals from cytokines and growth factor receptors in the plasma membrane (PM) to the nucleus, where they alter gene transcription.  Because of this transcriptional regulatory role, STAT3 also plays a part in regulating transcription of many critical genes that are involved in apoptosis, cell differentiation, immune response, tumor formation and more.  Using a
