Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human MED13 recombinant protein (Position: L61-Y240). (reported region: L61-Y240).
- Molecular weight context: reported MW: 300 kDa; calculated MW: 34482 MW
- Reactivity: Human,Mouse
- Applications: ELISA, Flow Cytometry, IF, ICC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
mediator complex subunit 13. Mediator complex subunit 13 is a protein that in humans is encoded by the MED13 gene. This gene encodes a component of the mediator complex (also known as TRAP, SMCC, DRIP, or ARC), a transcriptional coactivator complex thought to be required for the expression of almost all genes. The mediator complex is recruited by transcriptional activators or nuclear receptors to induce gene expression, possibly by interacting with RNA polymerase II and promoting the formation of a transcriptional pre-initiation complex. The product of this gene is proposed to form a sub-complex with MED12, cyclin C, and CDK8 that can negatively regulate transactivation by mediator. Functional note: Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. Reported localization: Nucleus. Expression/tissue context: Ubiquitous.
Research relevance and current trends
- Epigenetics and Nuclear Signaling: Researchers commonly examine how MED13 relates to this theme using model systems and orthogonal readouts.

Common research applications
- Western blotting: compare relative MED13 levels across conditions; band patterns may reflect isoforms and processing.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
- Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
