Anaerobe Knock-Out Vectors

Anaerobe Knock-Out Vectors


Knock-out vectors are available for the generation of mutants in a range of anaerobes in a classic two-step process by allelic exchange using the counter selection marker codA (cytosine deaminase) or pyrE (orotate phosphoribosyltransferase)

[1] codA-based plasmids pMTL-SC7215, pMTL-SC7315 & pMTL-SC7515, previously exemplified in Clostridioides difficile and Clostridium acetobutylicum and based on the pBP1, pCB102 or pIM13 replicons, respectively.

[2] pyrE-based plasmids pMTL-ME3 & pMTL-GL3, carrying either the pIM13 replicon or none at all (suicide), respectively. Exemplified in C. acetotobutylicum and C. beijerinckii, respectively.

[3] pyrE-based plasmids pMTL-YN3 and pMTL-YN4, based on the pCB102 and pBP1 replicons and exemplified in different strains of Clostridioides difficile.

[4] A suicide vector carrying both a pyrE and codA counterselection markers for the direct selection of in-frame deletions in C. acetobutylicum.

[5] pyrE-based suicide vector pMTL-JPB22 exemplified in Acetobacterium woodii.

Vectors supplied as a pair at a concentration of 50ng/µl DNA and are ready to be transformed into E. coli. Each pair costs 80 GBP plus postage at a rate dependent on destination - postage added at check-out.
