Plasmid name: pMacBLAL2HI (LMBP 2316)
|Price category:||Cat. 1 (cf. price list)|
|Status:||GeneCorner non-core plasmid|
|Cloned DNA:||Ampicillin resistance gene (amp)
Human immunoglobulin γ3 cDNA (hIG3); heavy chain hinge region
|Terminator:||Phage fd terminator|
|Selection marker:||Ampicillin (amp)
|Replicon:||Escherichia coli plasmid pMB1 origin
Phage f1 origin
|Host range:||Escherichia coli|
|Parental clone:||pMac254mSA; pBR325OMMBfmA|
|Further information:||The plasmid was constructed by introducing the HinFI (nucleotide position 4828; filled in with Klenow) - RsaI (nucleotide position 5184) fragment from pBR325OMMBfmA anticlockwise in the SacI opened and blunted (with T4 DNA polymerase) pMac254mSA vector.
This phasmid leads to the expression of a fusion protein in which 10 additional amino acids (from the VH region of OMMB) are present between the β-lactamase gene and the first hinge region (H1) of the human γ3 heavy chain. The translation of this fusion protein terminates 2 amino acids behind the fourth hinge region (H4), caused by the introduced termination codon in the CH2 domain; hence, CH2f is no longer translated.
The sequence of the inserted hIG3 fragment was obtained from Genbank (Release 55; Locus : HUMIGHAF') and contains some non-identified nucleotides (indicated by N).
The fusion product still provides resistance to ampicillin.
The f1 part of the plasmid contains the F1-ori, but also the sequence around the gene II promoter; the two TRP terminators at the end of the cam gene are not present.
Name mentioned in De Sutter et al., (1992) is pMacBlaL2Hi.
Other name of the plasmid is pMac254BLAVHfHI.
