|Further information:||The plasmid was constructed by inserting the EcoRI-HindIII fragment (sites filled-in with Klenow DNA polymerase) of pSP64GSHIFNBSNNT, containing the human IFNβ gene, into the unique XhoI site (filled in with Klenow DNA polymerase) of pCAGGS. pSP64GSHIFNBSNNT is derived from pSP64GSHIFNBNT (SacI opened, blunted (T4 exonuclease) and ligated with the filled-in (Klenow DNA polymerase) NotI-SFiI linker).
pCAGGSHIFNB2 is useful for highly efficient expression of human IFNβ under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.
Human IFNβ, used as a stuffer, can be excised as a SfiI fragment in this plasmid. The SfiI sites of the vector are non-compatible (repeated inverse). The human IFNβ gene can be excised from pCAGGSHIFNB1 as SfiI-NotI fragment.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of the hIFNβ cDNA corresponds with the EMBL Nucleotide Sequence Database accession number V00546.1.
Other name of the plasmid is pCAGGS-Sfi-Sfi-hIFNB.
