The best company out there right now is RetrievalNet, http://www.RetrievalNet.com\n\nThey can offer you secure underground storage and also electronic document retrieval on demand. Fits exactly what you are trying to do.

DNA comparison by electrophoresis. I've seen kits available in school divisions for science classes. On a similar note: paper chromatography to check if the composition of ink between samples are same or different.

One good one:\n\nDNA replication is much more resistant to errors ... so DNA molecules can be *much* longer than RNA and still survive replication.  This supports the stable propagation of a much larger number of genes (tens of thousands of genes) from generation to generation without degradation.

Storage - Bulk flax seed which is clean, dry and of good quality, can be stored at room temperature for up to a year. For optimum freshness, ground flax seed should be ground as needed. Unused ground flax seed can be refrigerated in an airtight container if it will be used in just a matter of days, or it can be stored in the freezer for about a month. Store your remaining bulk flax seeds in a dark, dry, and cool place.\n\nRecommended Daily Usage - To get the maximum benefits from flax seeds we recommend using 3 tbsp of ground flax seed per day.\n\nOne tablespoon of ground flax seeds and three tablespoons of water may serve as a replacement for one egg in baking by binding the other ingredients together, and ground flax seeds can also be mixed in with oatmeal, yogurt, water (similar to Metamucil), or any other food item where a nutty flavour is appropriate. [citation needed] Flaxseed oil is most commonly consumed with salads or in capsules.

You may create password-protected archive, where you can aggregate all the files you need.\nIt can be done in different ways for different archivers, but usually it's very simple.

I know you can use saliva or blood.  Although, this is kind of hard to test for without the person knowing.  I have done a lot of research in this subject.  Any type of DNA sample works, it is just a matter of how much you are willing to pay to find out this information.  Urine is the cheapest at about $20 for a test.

"DNA" testing is not sequence testing.  DNA is made up of nucleic acids (A, C, G, T).  In typical testing, the sample (blood, saliva, hair, skin) is treated so that the DNA material within the cells are extracted.  However, to actually sequence it against a known sample would take ages (i.e. the human genome project).  What forensics testing does is actually subject DNA material to enzymes that make specific cuts in the DNA strands that result in "characteristic" fragments or pieces in the DNA (in regions with high inter-individual variability).  So when these fragments are identified, it is matched against others who may or may not have the same fragment patterns (i.e. 1 out of 20,000 people will have an identical pattern).

what for? for a DNA gel to separate 1000 bp to 10000 bp I'd try a 0.7 % gel (i.e. 1.4g in 200 ml). and run it for 30-45 min (watch the bromophenol blue) this is about 500bp

That's all you get I'm afraid. To record longer samples you will need to download an audio recorder/editor. There are a million out there and they're all pretty bad unless you pay for one.\n\nI used to use CoolEdit Pro but then Adobe bought it and now it's like $1,000 for the package.

A database will work very well for what you need. MS Access is the only one I have personal experience with. I'm sure there are better apps out there. Create a query based on the cert expiration date and run it as needed.
