Bacterial Strains and Competent Cells

JM109 is a K strain that is recA- and endA- to minimize recombination and improve the quality of plasmid DNA. In addition, the cells carry the F´ e...

HB101 cells are recA-, which minimizes recombination events, and contain a restriction-minus background (hsdS20) that allows better representation ...

BL21(DE3)pLysS Competent Cells allow high-efficiency protein expression of any gene that is under the control of a T7 promoter and has a ribosome b...

The Single Step (KRX) Competent Cells are designed for efficient transformation and tightly controlled protein expression. These cells consolidate ...

NM522 contains an F' episome, which is required for production of ssDNA and for blue/white color selection. To maintain the F', NM522 should be gro...

Bacterial Strain LE392 is used for both genomic and cDNA cloning. LE392 lacks the E. coli K restriction system but is rec+. It is a permissive hos...

Bacterial Strain JM109(DE3), derived from JM109, contains a chromosomal copy of the gene for T7 RNA polymerase. JM109(DE3) is used for the high-lev...

Bacterial Strain JM109 is a useful host for transformation of pGEM Vectors and for production of single-stranded DNA from M13 or phagemid vectors. ...

BMH 71-18 mutS and ES1301 mutS are mismatch repair minus strains of E. coli. Use of these strains prevents repair of the newly synthesized unmethyl...
