Product Overview
This rabbit polyclonal antibody targets MMS19 nucleotide excision repair protein homolog in human and mouse samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 113.3 kDa, and the supplier reports an observed band at about 113 kDa.
MMS19 is a component of the cytosolic iron-sulfur assembly (CIA) machinery. It acts as an adapter that delivers iron-sulfur clusters to target proteins involved in DNA metabolism, such as the helicase XPD, so it supports DNA repair, DNA replication and genome stability.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Mouse) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human Caco-2 cells, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human bladder urothelial carcinoma tissue, human colorectal adenocarcinoma tissue, human placenta tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): HeLa cells.
Samples with a confirmed signal (flow cytometry): HeLa cells.
Immunogen
Recombinant human MMS19 fragment (Glu239–Arg998), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places MMS19 nucleotide excision repair protein homolog in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Ubiquitously expressed with higher expression in testis. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
