Trans2-Blue Chemically Competent Cell is specifically designed for chemical transformation of DNA. It permits a transformation efficiency of over 109 cfu/μg DNA (tested by pUC19 plasmid DNA). The competent cell is resistant to tetracycline (TetR) and chloramphenicol (CamR).


TetRΔ(mcrA)183Hte[F′{proAB lacIq lacZΔM15Tn10(TetR)AmyCamR}]Δ(mcrCB-hsdSMR-mrr)173 endA1supE44 thi-1 recA1 gyrA96 relA1


• High transformation efficiency (>1×109cfu/μg DNA).

• Suitable for larger plasmids and recombinant products.

• Reduced preference for plasmid size, suitable for library construction.

• Used in 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
