Rapid Protocol for Preparation of Electrocompetent Escherichia coli and Vibrio cholerae

DOI: 10.3791/50684-v
What you'll learn
  • ✓ Prepare electrocompetent E. coli and V. cholerae cells using rapid protocol
  • ✓ Transform electrocompetent bacteria via electroporation efficiently
  • ✓ Evaluate transformation success using representative results
Protocol

Electroporation is a commonly employed method for introducing DNA into bacteria in a process known as transformation. Traditional protocols for the preparation of electrocompetent cells are time consuming and labor intensive. This article describes an alternate, rapid, and efficient method for the preparation of electrocompetent cells presently employed by some laboratories.

Difficulty
intermediate
Total time
~2-3 hours
Biosafety
BSL-1

Steps

1
Prepare bacterial cultures, tools, and reagents
