pSP64 Poly(A) Vector Technical Bulletin

Instructions for Use of Product(s)

Literature # TB052

The Riboprobe® System Vector pSP64 Poly(A) can be used as a standard cloning vector and for in vitro transcription from the SP6 promoter. The pSP64 Poly(A) Vector also can be used to generate poly(A)+ transcripts in vitro. The vector has a stretch of 30 dA:dT residues inserted between the SacI and EcoRI sites. Therefore, when foreign DNA is cloned into any polylinker site other than EcoRI, (HindIII, PstI, SalI, AccI, HincII, XbaI, BamHI, AvaI, SmaI or SacI), linearization of the recombinant plasmid with EcoRI allows the use of SP6 RNA polymerase in vitro to prepare RNA copies of inserted sequences that contain a synthetic 3′ "polyA" tail of 30 residues.
