Hi everybody,

let´s say I wanted to try out DNA Profiling at my home lab. I think of the normal procedure with analyzing the short tandem repeats.
Does anybody of you know where to get a lab protocol?
Is it a very complicated procedure or can it quite easily be done at your home lab?
What kind of equipment is required for that?

Thank you very much

Mike

Everything but the sequencing can be done at a home lab(the sequencing can be done but would require much more expensive equipment and reagents).

Basically, all that you need are a PCR machine and reagents. This will run you around $300-$500. After you run the experiment you can send off the samples to a number of sequencing companies who will send you back the DNA sequence for around $4-$7.

We sell most all of this stuff. Contact me if you want me to help guide you through experiments.

Thanks,

Hi, 

First you need to know if you want to identify sample (ex: cat or dog) or if you want to identify alleles (ex: actn3 r/x)
Try google scholar and sci hub to search for related papers

Second, you need to desing your primers. If you wish to identify samples, that's a PCR plus some sequencing (yes, 4-7e/sample, even 2.1e). If you wish to identify alleles, thats with a qPCR and it gets "expensive".

The protocol is "easy": dna extraction (look for some dna extraction columns at ebay or aliexpress, even ask for free sample.I got 100uds form a usa distributor). Then, prepare the mix is trivial (you need mg buffer, taq, primers...). 

If you are looking for STR with different lenght, with a PCR and an agarose gel it should be enough, otherwise you need to use some sanger sequencing (macrogen, bgi, source biosciences... a lot of them. even research centers if you have some friend inside)

As always, if you explain more your project, we can give you a better approach
