pFB载体描述 The Agilent pFB and pFB-Neo plasmid vectors for retroviral gene delivery and expression are derived from the Moloney murine leukemia virus (MMLV) and can be used to produce high titer viral stocks with MMLVbased packaging cell lines.1,2 Both vectors contain the bacterial origin of replication and ampicillin-resistance gene from pBR322, an extended MMLV packaging signal (ψ+), and a multiple cloning site (MCS) located between the MMLV 5′ and 3′ long terminal repeat sequences (LTRs).
The pFB vector is a minimal MMLV-based vector that can accommodate larger inserts than pFB-Neo. The pFB vector does not contain any exogenous sequence other than the sequence of the MCS.
The pFB-Neo vector differs from the pFB vector only by the presence of a cassette consisting of the internal ribosome entry site (IRES) from the encephalomyocarditis virus (EMCV) and the neomycin-resistance gene (neor). The open reading frame (ORF) for the neor gene is positioned downstream of the MCS and follows the IRES. A dicistronic message encoding the gene of interest and the neor gene is expressed from the viral promoter within the 5′ LTR. pFB载体限制性酶切位点 pFB, 5117 bp version 013001
