ΔrecA1398 endA1 tonA Φ80ΔlacM15 ΔlacX74 hsdR(rK- mK+)
- From Invitrogen
- Doubling time approx. 50 min and supposedly fastest growing chemically competent cloning strain available
- Mach1 cells are derivatives of E. coli W strains (ATCC 9637, S. A. Waksman), rather than E. coli K-12. This may have implications for BL-1 status for some facilities (apparently not for MIT).
- See Bloom04 patent for details on the construction and properties of this strain.
