簡單介紹:
5 alpha Chemically Competent Cell
詳情介紹:
5α Chemically Competent Cell is designed for chemical transformation of DNA, with blue/white selection, reduced recombinantion of cloned DNA, and a transformation efficiency of over 108 cfu/µg DNA (tested by pUC19 plasmid DNA).

The genotype is: F-φ80d lacZΔM15 Δ(lacZYA-argF) U169 end A1 recA1 hsdR17 (rk-, mk+) supE44λ- thi-1 gyrA96 relA1 phoA.

The 1 ml size consists of 10 × 100 µl Competent Cells, and 20 μl (0.1 ng/μl) Control Plasmid pUC19.

Directions for use

Recommended Protocol:

  • Equilibrate a water bath to 42 °C. Bring a vial of SOC medium or LB medium to room temperature. Warm selective plates to 37 °C for 30 minutes.
  • Thaw 100 µl of 5 alpha Chemically Competent Cell on ice. Aliquot 50 µl of cells into a pre-chilled 1.5 ml tube, then add target DNA (1-5 µl). Do not mix by pipetting up and down. Leave on ice for 30 minutes.
  • Heat-shock the cells for 45 seconds at 42 °C, without shaking. Immediately transfer to the tube to ice. Leave on ice for 2 minutes without shaking.
  • Add 500 µl of prewarmed SOC medium or LB medium (without antibiotics) into the tube. Mix well and shake at 37 °C for 1 hour at 200 RPM for cell recovery and expression of antibiotic resistance.
  • Spread 20-200 µl from each transformation vial onto a pre-warmed selective plate. Cells that have not been plated can be stored at 4 °C and plated the next day if required.
  • Invert the plates and incubate at 37 °C overnight.
  • Select colonies and analyse by restriction enzyme digestion, PCR or sequencing.
  • Note:

    Higher efficiency transformation can be achieved by transforming cells immediately following thawing. Avoid repeated thawing. All samples and reagents require gentle handling throughout the entire procedure.
