|Further information:||The plasmid was constructed by converting pcDNA3 to a Gateway destination vector as follows: 1) The Gateway reading frame cassette A (rfA, from Invitrogen) was amplified with primers containing an EcoRV site, the HA epitope and an XhoI site. 2) The PCR product and the vector pcDNA3 (Invitrogen) were digested with EcoRV and XhoI and ligated together, resulting in pdcDNA-HA.
pdcDNA-HA is a Gateway destination vector, containing the the ccdB gene flanked by the bacteriophage λ attR recombination sites.
pdcDNA-HA is designed for fusing a gene of interest to the N-terminal HA epitope according to the Gateway Cloning Technology (Invitrogen) and for high-level, constitutive, native expression of this gene in mammalian cells under control of the human CMV-IE promoter and enhancer.
A Gateway entry clone, containing the gene of interest flanked by the λ attL recombination sites, recombines with the attR sites of the destination vector, replacing the ccdB gene. Standard E. coli strains with the unreacted destination vector or with the by-product plasmid retaining the ccdB gene will fail to grow. Thus, this negative selection provides high-efficiency recovery of only the desired clones. The chloramphenicol resistance gene located between the two attR sites permits counterselection.
Unlike pcDNA3, pdcDNA-HA has not been shown to provide resistance to kanamycin.
This Gateway destination vector is compatible with the human orfeome library which is also available at BCCM/GeneCorner.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727252.1.
The presence of a second enhancer in the SV40 early promoter was shown by sequence analysis at LMBP.
The region from the T7 promoter up to nucleotide position 2062 was sequenced by LMBP.
Other name of the plasmid is pDEST-HA.

|Authenticity test:||Restriction enzyme pattern analysed at GeneCorner: BamHI, BglII, EcoRV/XhoI and NcoI.
As compared to the nucleotide sequence file, the expected 276 bp BamHI fragment is approximately 425 bp. Furthermore, the 1124 bp NcoI fragment seems to be approximately 1300 bp. However the nucleotide sequence was confirmed by sequencing analysis at GeneCorner.
