NEB Cloning Competent E. coli Sampler

Product Introduction

Not sure which cloning strain to choose? The NEB Cloning Competent E.coli Sampler allows you to sample 4 of our popular chemically competent strains. The Sampler includes two 0.05 ml tubes of each of the following strains (as well as outgrowth medium and control):

  • NEB 5-alpha: Our best-selling strain for basic cloning; Derivative of the popular DH5α. It is T1 phage resistant and endA deficient for high-quality plasmid preparations.
  • NEB 10-beta: derivative of the popular DH10B. It is T1 phage resistant and endonuclease I (endA1) deficient for high-quality plasmid preparations.
  • NEB Stable: Ideal for isolation of plasmid clones containing repeat elements and unstable inserts. Useful for isolating and propagating retroviral/lentiviral clones
  • NEB Turbo: Features fast colony growth (6.5 hours) and tight expression control (lacIq). Isolate DNA after only 4 hours of growth

Product Notes

  1. CAUTION: This product contains DMSO, a hazardous material. Review the MSDS before handling.

  2. STORAGE AND HANDLING: Competent cells should be stored at -80°C. Storage at -20°C will result in a significant decrease in transformation efficiency. Cells lose efficiency whenever they are warmed above -80°C, even if they do not thaw.
