Highlights
- Quick (2 minute) desalting and recovery of ultra-pure DNA from enzymatic reactions (e.g., PCR and endonuclease digestions), cell-free lysates, etc.
- Column design allows DNA to be eluted at high concentrations into minimal volumes.
- Eluted DNA is well-suited for use in PCR, DNA sequencing, DNA ligation, endonuclease digestion, RNA transcription, radiolabeling, arrays, etc.
Description
Detergent Tolerance | ≤5% Triton X-100, ≤5% Tween-20, ≤5% Sarkosyl, ≤0.1% SDS |
---|---|
Elution Volume | ≥ 25 µl |
Equipment | Microcentrifuge |
Purity | Highly-pure DNA is eluted with water and is especially well suited for sequencing, ligation reactions, and restriction endonuclease digestions. |
Sample Source | DNA from PCR, endonuclease digestions, DNA modification reactions, isotope/fluorescence labeling reactions, etc. |
Size Range | 50 bp to 23 kb |
Yield | ≤ 25 µg total DNA can be recovered.For DNA 50 bp to 10 kb the recovery is 70-90%. For DNA 11 kb to 23 kb the recovery is 50-70%. |
Q1: What is the difference between capped and uncapped?
The only difference is the cap. Everything else between the columns (max capacity, column matrix, etc.) is the same. Unsure which to use? It mainly comes down to preference. Some people like the capped columns for easy labeling or added security while others like the uncapped columns for faster sample processing.
Q2: What is the minimum input volume of DNA sample?
Working with volumes below 50 µl can result in decreased recovery. Zymo Research recommends raising the starting volume to 100 µl with water to ensure optimal binding conditions.
Q3: How many times can columns be reloaded?
Zymo Research recommends reloading columns no more than 5 times, as binding efficiency might decrease.
Q4: What happens if more DNA was loaded on the columns than the stated maximum binding capacity?
Oversaturation of the column can result in total DNA loss due to clogging of silica matrix.
Q5: How can I process naked DNA stored in DNA/RNA Shield?
Use the standard protocol (add 2 or 5 volumes of DNA binding buffer depending on DNA size).
Q6: What is the lower limit and minimal amount of DNA that can be recovered?
Picogram levels of DNA can be recovered. The limitation is based on sensitivity of detection method.
Q7: What should I do if I did not add ethanol to the DNA Wash Buffer before starting?
The DNA will be eluted off the column during the wash step. Rebind samples using the appropriate amount of DNA Binding Buffer and wash the column with the properly prepared wash buffer.
“This kit performed as described. I was able to obtain good quality and yield of the DNA -better than with a couple of competitor"s kits.”
-Kathleen B. (SUNY-ESF)
“The simple steps and washing instructions were excellent. DNA was ready for use for PCR and gave strong results.”
-Tyler C.
“It only took 2 minutes for the total procedure - shorter than my current method of PCR purification.”
-Marissa V. (Harvard Medical School)
