Parental clone: pEGFP-N3; pHcRed1
Further information: The plasmid was constructed as follows: 1) first, the pPTB-EGFP vector was made by cloning a BamHI/EcoRI PCR amplicon, containing the human PTBP1 cDNA, in the BamHI/EcoRI opened pEGFP-N3 vector; 2) the HcRed1 coding sequence was obtained by PCR from the pHcRed1 template; 3) finally, the EGFP coding sequence was removed from the pPTB-EGFP vector by digestion with BamHI and HpaI and replaced by the BamHI/HpaI digested HcRed1 amplicon.
HcRed1, whose excitation and emission maxima respectively occur at 588 nm and 618 nm (+-)4 nm, was generated by mutagenesis of a non-fluorescent chromoprotein from the reef coral Heteractis crispa (HcRed-2A). The HcRed1 coding sequence has been human codon-optimized for higher expression in mammalian cells.
The neomycin resistance cassette, consisting of the SV40 early promoter, the neomycin/kanamycin resistance gene of Tn5, and HSV-TK polyadenylation signals, allows stably transfected eukaryotic cells to be selected using G418. The E. coli β-lactamase promoter upstream of this cassette expresses kanamycin resistance in E. coli.
The neomycin resistance coding sequence does not carry the PstI site anymore, neither the BssHII site.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726976.1.
The nucleotide sequence of the human PTBP1 cDNA corresponds with the Genbank Nucleotide Sequence Database accession number NM_002819.4.
Other name of the plasmid is pcPTB-HcRed.
