Mammalian cells; SV40 permissive cells
|Further information:||The plasmid was constructed as follows: 1) N-terminal and C-terminal fragments of the mA20 coding sequence were generated by PCR. 2) These PCR fragments were fused, resulting in the mA20 coding sequence with the internal deletion of the codons 505 up to and including 590. 3) This 2122 bp XhoI-BglII PCR fragment was inserted into the XhoI-BglII opened pCAGGS2 vector.
pCAGGS-FLAGmA20d4 is useful for highly efficient expression of partial mA20 under the control of the AG promoter and the human CMV-IE enhancer in various mammalian cells.
The expression cassette is provided with an N-terminal FLAG epitope tag, followed by a KpnI site.
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 mA20 cDNA corresponds with the EMBL Nucleotide Sequence Database accession number U19463.1 and adapted to the sequence analysis results of the Department of Biomedical Molecular Biology (Ghent University, Belgium). The following difference is observable: the nucleotide T at position 2096 is substituted by a C- residue, resulting in a Leu/Pro replacement.
Other names of the plasmid are pCAGGS-FLAGmA20(Δ505-590) and pCAGGS-007-047#1.
