Competent Cells
-
Cells Preparation : - Thaw competent cells rapidly by immersing frozen tubes in a 37°C water bath
- Immediately, add one volume of SpII + EGTA to the Thawed cells; mix gently
- In a sterile test tube add competent cell (0.2~0.5 ml) to the DNA solution (<0.1 ml) and incubate in a roller drum at 37.
- Dilute the transformed cells as appropriate in T base containing 0.5% glucose and plate immediately onto selective media.
Digestion : - Select restriction enzymes to digest your plasmid. Determine an appropriate reaction buffer by reading the instructions for your enzyme.
- DNA
- Restriction Enzyme(s)
- Buffer
- dH2O up to total volume
- Incubate tube at appropriate temperature (usually 37°C) for 1 hour.
- Always follow the manufacturer’s instructions.
- To visualize the results of your digest, conduct gel electrophoresis
In a 1.5mL tube combine the following:
Mix gently by pipetting.
Vector Preparation : Combine the following in a PCR or Eppendorf tube:
- 25ng Vector DNA
- 75ng Insert DNA
- Ligase Buffer (1μL/10μL reaction for 10X buffer, and 2μL/10μL reaction for 5X buffer)
- 0.5-1μL T4 DNA Ligase
- H20 to a total of 10μL
Incubate at room temperature for 2hr, or at 16°C overnight (following the manufacturer’s instructions).
