DNA Rehydration Solution – Research Use Only

DNA Rehydration Solution is a biotechnology-grade, ready-to-use aqueous buffer optimized for the efficient resuspension and rehydration of purified or dried DNA. Supplied as a 50 mL clear solution, this reagent is formulated to maximize DNA recovery, maintain integrity, and minimize degradation during reconstitution from pellets, dried spots, or lyophilized samples.

Scientific Overview

Proper rehydration is a critical step in DNA sample preparation that directly impacts yield, integrity, and performance in downstream applications such as PCR, sequencing, cloning, and forensic analysis. DNA Rehydration Solution is a specialized buffer designed to gently and efficiently dissolve DNA pellets or dried samples while protecting against degradation, aggregation, and adsorption to tube surfaces. Its optimized composition helps maintain the native structure of DNA and improves solubility compared to plain water or generic TE buffers.

This DNA Rehydration Solution is suitable for:

• Resuspension of ethanol-precipitated or column-purified DNA
• Rehydration of DNA from dried blood spots, buccal swabs, or forensic samples
• Preparation of DNA stocks for long-term storage or immediate downstream use
• Minimizing loss due to adsorption or incomplete dissolution
• Standardization of DNA concentration in high-throughput workflows

Usage & Handling Guidance

Store at room temperature (RT). The solution is ready-to-use. Add an appropriate volume directly to the DNA pellet or dried sample and pipette gently to resuspend. Incubate at room temperature or 37 °C for 5–30 minutes with occasional gentle mixing if needed for complete dissolution. Avoid vortexing vigorously to prevent shearing of high-molecular-weight DNA.

• Recommended applications: DNA resuspension, reconstitution of dried samples, and preparation for PCR, sequencing, or storage
• Typical volume: Use 10–100 µL per µg of DNA or scale according to pellet size (optimize for desired final concentration)
• Stability: Stable at RT; for long-term storage of reconstituted DNA, aliquot and freeze at –20 °C
• Handling: Use DNase-free tubes and pipette tips; gentle pipetting recommended to preserve DNA integrity

Frequently Asked Questions (FAQ)

• What is the purpose of this solution?
  It is specifically formulated to efficiently rehydrate and resuspend purified or dried DNA while preserving integrity and maximizing recovery.
• Can I use water or TE buffer instead?
  Plain water or standard TE may result in lower recovery or incomplete dissolution. This specialized solution is optimized for better performance.
• How much volume should I use?
  Use 10–100 µL per µg of DNA or scale according to pellet size. Aim for your desired final concentration (e.g., 0.1–1 µg/µL).
• Is this solution DNase-free?
  Yes. It is prepared under biotechnology-grade conditions with ultrapure water and 0.22 µm filtration to minimize nuclease contamination.
• How should I store reconstituted DNA?
  After rehydration, aliquot and store at –20 °C for long-term stability. Avoid repeated freeze–thaw cycles.
