The pSP73 Vector offers a wide range of restriction sites, providing greater versatility in cloning and transcription of RNA in vitro. The pSP73 Vector contains the SP6 and T7 RNA polymerase promoters and a unique multiple cloning region, which includes restriction sites for BglII, EcoRV, ClaI, EcoRI, SacI, KpnI, SmaI, BamHI, XbaI, SalI, AccI, PstI, SphI, HindIII, PvuII and XhoI. The pSP72 and pSP73 Vectors are essentially identical except for the orientation of the multiple cloning region.
