Product Overview
This rabbit polyclonal antibody recognizes mediator of RNA polymerase II transcription subunit 13 (gene MED13) in human and mouse samples and is validated for ELISA, flow cytometry, ICC/IF and Western blot. The predicted molecular weight is 239.3 kDa, and the supplier reports an observed band at about 300 kDa.
MED13 is a subunit of the CDK8 kinase module of the Mediator complex, where it anchors the module to the core Mediator. Mediator bridges gene-specific transcription factors and the RNA polymerase II machinery. MED13 is studied in transcriptional regulation and in cardiac control of systemic energy metabolism, and variants are linked to neurodevelopmental disorders.
