Document 1266 DOCN M9591266 TI Polyclonal rabbit antisera that detect the Vpr protein of SIVSM and SIVMAC on immunoblots of purified virions. DT 9509 AU Newman MA; McPherson SA; Fletcher TM 3rd; Kappes JC; Hahn BH; Department of Medicine, University of Alabama at Birmingham; 35294, USA. SO AIDS Res Hum Retroviruses. 1995 Mar;11(3):405-8. Unique Identifier : AIDSLINE MED/95306144 AB Antisera suitable for detection of SIVSM or SIVMAC Vpr proteins on Western blots of purified virions are currently not available. We have expressed the Vpr protein of SIVSMPBj1.9 in a gst-based prokaryotic expression system and used it to raise polyclonal antisera in rabbits. Two immune sera were obtained that specifically recognized both cell- and virion-associated Vpr protein on immunoblots of three different SIV isolates (SIVSMPBj1.9, SIVMACBK28, and SIVMAC239). Because Vpr is believed to play an important role in HIV/SIV replication and pathogenesis, these reagents will allow the extension of functional analyses of this protein to a broader spectrum of viruses. Both antisera and the gst-Vpr expression plasmid have been submitted to the NIAID AIDS Research and Reagent Program and are available to interested investigators.
