Product Overview
This rabbit polyclonal antibody detects mediator of RNA polymerase II transcription subunit 15 (gene MED15) in human, mouse and rat samples and is validated for ELISA, flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 86.8 kDa, and the supplier reports an observed band at about 97 kDa.
MED15 is a subunit of the tail module of the Mediator complex, the coactivator that conveys signals from DNA-bound transcription factors to RNA polymerase II. The tail binds activation domains of many transcription factors, including those controlling lipid and cholesterol metabolism. MED15 is studied in transcriptional activation and gene regulation.
