Trans109 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).

Genotype
endA1 recA1 gyrA96 thi-1 hsdR17 (rk^-, mk⁺) relA1 supE44 D (lac-proAB) [F′traD36 proAB la^qIqZΔM15]

Features
• High transformation efficiency: >10⁸ cfu/μg ( pUC19 DNA).
• The lowest homologous recombination favorable for plasmid DNA preparation.
• Routine cloning.
• Blue/white selection.
