Plasmid name: pBLhIL6LUC (LMBP 3287)
|New search||Print data sheet|
|Price category:||Cat. 1 (cf. price list)|
|Status:||GeneCorner non-core plasmid|
Photinus pyralis (firefly) luciferase gene (LUC)|
|Promoter:||Human interleukin 6 promoter (IL6)
Escherichia coli lac operon promoter
|Terminator:||Simian virus 40 polyadenylation signal (SV40 polyA)|
|Selection marker:||Ampicillin (amp)|
|Replicon:||Escherichia coli plasmid pMB1 origin|
|Host range:||Escherichia coli; preferably recombination-deficient strains
|Parental clone:||pSV2L5; pBLHIL6CAT|
|Further information:||The plasmid was constructed as follows: the luciferase gene of pSV2L5 was inserted as a BamHI-HindIII fragment between the XhoI and XmaI (SmaI) sites of pBLHIL6CAT, replacing the chloramphenicol acetyltransferase gene. The restriction sites involved were filled in with Klenow DNA polymerase, restoring the HindIII, BamHI and XmaI (SmaI) sites.
The resulting plasmid allows functional analysis of the human IL6 promoter.
This plasmid contains the SV40 small t-antigen splicing signal. It also contains three SV40 polyadenylation segments. Hence, the possibility might exist that the plasmid could loose information by homologous recombination.
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 genomic hIL6 DNA corresponds with the EMBL Nucleotide Sequence Database accession number AC073072.11. However, the C nucleotide at promoter position -174 (polymorphism mutant) was changed into a G nucleotide (wild type).
Other name of the plasmid is 1168Luc.
