DNA Stable Plus A DNA Preservation Product

DNAstable® Plus

Stabilize and store purified DNA at Room Temperature

  • Next generation liquid preservative for purified DNA - at all temperatures
  • Liquid format option compatible with automation and sample handling workflows
  • Recover high amounts of DNA and analyze instantly without further purification
  • Compatible with most downstream applications, e.g., PCR, RT-PCR, SNP analysis, DNA sequencing, etc.
  • Cost-effective, eco-friendly solution to freezer crawl and lab space management

DNAstable® Plus enables you to preserve, store and ship your purified DNA samples at room temperature in liquid and liquid-to-dry formats. It offers flexibility with thermostability at extreme temperatures, and the ability to handle high concentrations of DNA. Recovery from the dry matrix is achieved within minutes by simply adding water. Your DNA sample is ready for downstream analysis without the need for any additional purification steps.

DNA stabilization can be achieved in two formats:

  1. Liquid Stabilization (short-term)
  2. Liquid-to-Dry (LD) Stabilization (long-term)

Figure 2: The gel image above shows protection of DNA samples stored in DNAstable Plus (conc: 50 ng/ul) for 6 months at 85°C in liquid-to-dry format compared to unprotected samples (NP; no visible bands). The positive controls are samples stored at 4°C.

Technical Data:

  • Downstream Analysis (qPCR) of genomic DNA stored dry for 6 months at various "STRESS" conditions.
  • DNAstable Plus protects genomic DNA under extreme stress conditions at +85°C in LD format.
  • DNAstable Plus does not cause any interference with downstream analysis.
  • DNA recovered from samples protected with DNAstable Plus (stressed at 60°C or 85°C) are similar to DNA recovered from stored at 4°C.

Figure 3: Human genomic DNA samples were stored for 6 months in a number of conditions, recovered and compared. From left to right: Control 4°C; Stored in DNAstable Plus at 60°C; Stored in DNAstable Plus at 85°C; Stored unprotected (TE) at 60°C; and Stored unprotected (TE) at 85°C (no DNA recovered). The control was a liquid whereas all other samples were recovered from a dried state.

Figure 5: DNA recovered after storage at +85°C for 3 months in dried format. Samples protected with DNAstable Plus (DSP) are recovered similar to -20°C controls. However, non-protected (NP) samples and competition "G" show no DNA recovery.
