Product Overview
Clone 18M47 is a rabbit monoclonal antibody that recognizes matrin-3 (gene MATR3) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 94.6 kDa, and the supplier reports an observed band at about 125 kDa.
Matrin-3 (MATR3) is an RNA- and DNA-binding protein of the nuclear matrix. It participates in retaining defective RNAs in the nucleus together with the SFPQ-NONO complex, binds m6A-modified mRNAs, and contributes to innate immune signaling against DNA viruses. Mutations in MATR3 are associated with ALS and distal myopathy, so it is studied in RNA metabolism and neuromuscular disease.

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).
Immunogen
Synthetic peptide based on the sequence of human matrin 3.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places matrin-3 in the nucleus matrix. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
