pBudCE4.1-hrGFP Description

pBudCE4.1-hrGFP plasmid was cloned into the hrGFP green fluorescent gene in pBudCE4.1 vector. When the pBudCE4.1 plasmid is used, it is best to use the strain without Tn5 gene, such as TOP10 and DH5 alpha T1, when E.coli clones are cloned. The best use of electrotransfer is to use TOP10, and the working concentration of bleomycin Zeocin recommends 25 u g/ml ~50 mu g/ml.

The pBudCE4.1 vector is designed to independently express two genes from a single vector in mammalian cells. The use of pBudCE4.1 to produce stable mammalian expression cell lines ensures that the copy number of each gene in the cell is equal. This can eliminate the change of expression caused by the difference of gene copy number. PBudCE4.1 can provide expression boxes with the following characteristics:

• CMV for high level transcription genes, which can be used for rapid detection of c-myc epitope tags and for simple purification of 6xHis sequences.

• EF-1 alpha promoters for highly expressed genes, which can be used for rapid detection of V5 epitope tags and for simple purification of 6xHis sequences.

Sh ble (ZeoR) gene for efficient selection of Zeocin in mammalian cells and E. coli.


pBudCE4.1 is a 4.6 kb vector designed for simultaneous expression of two genes in mammalian cell lines. The vector contains the human cytomegalovirus (CMV) immediate-early promoter and the human elongation factor 1α-subunit (EF-1α) promoter for high-level, constitutive, independent expression of two recombinant proteins (see page 13 for more information on the EF-1α promoter). Features of the vector allow detection and purification of expressed proteins (see pages 15–16) for more information). High-level stable and transient expression studies can be carried out in most mammalian cell types. In addition to the two promoters, the vector contains the following elements:
        • C-terminal peptides encoding the myc (c-myc) epitope or the V5 epitope and a polyhistidine (6xHis) metal-binding tag for detection and purification of recombinant proteins
        • Zeocin™ resistance gene for selection in E. coli and creation of stable, mammalian cell lines (Mulsant et al., 1988) (see pages 18–19 for more information)
        • SV40 origin for episomal replication in cell lines that are latently infected with SV40 or that express the SV40 large T antigen (e.g., COS7) pBudCE4.1/lacZ/CAT is included for use as a positive control for transfection, expression, and detection in the cell line of choice.
        pBudCE4.1 is an improved version of pBudCE4. During construction of the original vector, an ATG was inadvertently created in the multiple cloning site (672–674 bp) 3′to the CMV promoter. Since it may interfere with proper translation of the cloned gene, this ATG was changed to ATT to create pBudCE4.1.
