1. For long term storage, store at -20°C. If samples need to be diluted, use TE or other buffer of minimal ionic strength. DNA may denature if diluted in dH₂0 and subsequently heated. Temperatures > 60°C may cause denaturation.
2. The cohesive ends of fragments 1 and 4 may be separated by heating to 60°C for 3 minutes.
3. 1X Gel Loading Dye, Purple, no SDS: 
   2.5% Ficoll®-400
   10mM EDTA
   3.3mM Tris-HCl (pH 8.0@25°C)
   0.02% Dye 1

1. Suggested Loading Protocol for N3014 & N3012
2. Suggested Loading Protocol for DNA Ladders & Markers

1. What are the overhangs on the DNA ladder fragments? Can I end-label them using the T4 polynucleotide kinase (PNK)? What about the Klenow fragment?
2. How can I quantify the amount of DNA in each band of a marker?
3. Why does my Lambda DNA molecular weight marker appear smeared and not represent the correct banding pattern?
4. Can I use Midori Green with the DNA Ladders from NEB?
5. Can I use SYBR^® and/or GelRed^® dyes with the DNA Ladders from NEB?
6. Why is my DNA Ladder floating out the wells and Why are there no bands visible in my DNA ladder gel lane?
