Product Overview
This rabbit polyclonal antibody recognizes mediator of RNA polymerase II transcription subunit 14 (gene MED14) in human samples and is validated for ELISA and Western blot. The predicted molecular weight is 160.6 kDa, and the supplier reports an observed band at about 160 kDa.
MED14 is a large central scaffold subunit of the Mediator complex, the coactivator that links gene-specific transcription factors to RNA polymerase II and the basal transcription machinery. It is needed to connect the head, middle and tail modules of Mediator, and it is studied in basic mechanisms of gene transcription.
