Trans1-Blue Chemically Competent Cell is specifically designed for chemical transformation of DNA. It permits a transformation efficiency of over 108 cfu/μg DNA (tested by pUC19 plasmid DNA). The competent cell is resistant to tetracycline (TetR).


recA1 endA1 gyrA96 thi-1 hsdR17 supE44 (rk-,mk+), relA1 lac [F' proAB lacIqZΔM15: Tn10 (TetR)]


• High transformation efficiency: >108 cfu/μg ( pUC19 DNA).

• TetR.

• Blue/white selection.


at -70 °C for six months


Higher efficiency transformation can be achieved by transforming cells immediately following thawing.

Avoid repeated thawing.

Gentle handling is required for the entire procedure.
