Product Overview
Clone 4F3 is a mouse monoclonal antibody that recognizes heterogeneous nuclear ribonucleoprotein D0 (gene HNRNPD) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 38.4 kDa, and the supplier reports an observed band at about 43–45 kDa.
hnRNP D (HNRNPD, also called AUF1) binds AU-rich elements in the 3′ untranslated regions of many short-lived mRNAs, such as those of cytokines and proto-oncogenes, and usually promotes their decay. It also binds telomeric single-stranded DNA and regulates translation of some clock gene mRNAs, and it is studied in mRNA turnover and inflammation.

Immunogen
Recombinant human hnRNP D/AUF1/HNRNPD fragment (Glu88–Asn246), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places heterogeneous nuclear ribonucleoprotein D0 in the nucleus and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
