Monoclonal antibody specific for Dhx9/NDHII/RHA.

Dhx9/NDHII/RHA is a member of the DEAH family of proteins, which possess a double-stranded RNA-binding domain (dsRBD) and a helicase domain. The DEAH protein family plays a critical role in RNA metabolism. DEAH family members function as ATP-dependent RNA helicases and regulation of transcription. In the present study, we report the establishment of a monoclonal antibody specific for Dhx9 using the rat medial iliac lymph node method. Immunoblot analysis using our antibody against Dhx9 detected full-length Dhx9. In addition, immunocytochemical staining using our antibody against Dhx9 revealed the nuclear localization of Dhx9. This monoclonal antibody against Dhx9 will allow for further detailed studies of Dhx9 expression.
