The pSP64 Poly(A) Vector 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 the inserted sequences that contain a synthetic 3' poly(A) tail of 30 residues.

The pSP73 Vector can be used as a standard cloning vector and also can be used for 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 site region.

The pUC/M13 Primers are designed for sequencing inserts cloned into the M13 vectors and pUC plasmids. These primers also can be used for sequencing other lacZ-containing plasmids such as the pGEM-Z and pGEM-Zf Vectors. The primers are purified by gel electrophoresis or HPLC. Primer Sequences: [Reverse (17mer)] 5'-d(CAGGAAACAGCTATGAC)-3', [Forward (24mer)] 5'-d(CGCCAGGGTTTTCCCAGTCACGAC)-3'.
