Description:
High stability, high efficiency, no heat shock step. For Research Use Only.

Applications:

  • Ideal for sub-cloning and scale-up applications
  • HB101 strain is a hybrid K12 x B bacterium, containing the recA13 mutation that minimizes recombination and aidsin insert stability. In addition, it carries the hsdS20(rB-mB-) restriction minus genotype which prevents cleavage of cloned DNA by endogenous restriction enzymes. HB101 strain does not support Alpha-complementation for blue/white screening. Transform efficiency is around 1.0x107 ~ 1.0x109 cfu/µg with pUC18 control DNA.

Recommended storage condition:
This product should be stored at -80°C. Thaw on ice only before use. Do not re-freeze.

Recommended reaction conditions:

  • Mix DNA with competent cells
  • Let stand on bench for 5 minutes
  • Direct plate
