NeoPrep mini

NeoPrep mini


  • Neo Biotech's miniprep kits (NB-60-0001) offer a fast and efficient way to extract pure plasmid DNA from Escherichia coli.
  • The process includes alkaline lysis of bacterial cells and DNA binding to silica under high salt conditions.
  • The resulting DNA is ideal for PCR, automated fluorescent sequencing, and various enzymatic applications.


Storage conditions and reagents preparation

All kit components can be stored at room temperature (20-25 °C) and are stable till the expiry date. Before use, add 1 mL of Buffer A1 to the RNase A vial and vortex. Transfer the resulting solution into the Buffer A1 bottle and mix thoroughly. Buffer A1 with RNase should be stored at 4 °C for frequent use and at -20 °C for infrequent use. Add 32 mL of 100% molecular biology grade ethanol to each bottle of buffer A4. Buffer A2 may form a precipitate upon storage. If necessary, dissolve the precipitate by warming the solution at 37 °C. Buffers A3 and AY contain guanidine hydrochloride. Wear gloves and goggles when using this kit.

Growing of bacterial cultures:


  • LB medium is recommended for bacterial cell cultivation, but rich media like 2xYT or TB can also be used.
  • Rich media promotes faster growth and early entry into the stationary phase compared to LB.
  • However, using rich media may lead to more dead or starving cells, resulting in partially degraded plasmid DNA and potential contamination with chromosomal DNA.
  • Overgrown cultures can contain excessive bacterial material, affecting lysis and precipitation steps.
  • To start, select a single colony from a selective plate and inoculate 1-5 mL of LB medium with the appropriate antibiotic.
  • Incubate for 12-16 hours at 37°C with vigorous shaking.
