- One of the most common laboratory Escherichia coli strains used for molecular cloning
- Derived from Escherichia coli K-12
- High transformation efficiency
- Appropriate host for α-complementation and blue-white selection
- Mutations in recA1 and endA1 in this strain provide better insert stability during cloning
- Can also be used for the assembly of DNA fragments (Kostylev, et al., 2015)
- DH5α is a trademark of Invitrogen Corp. (Sigma-Aldrich)
