What factors effect this? (sunlight, temperature, humidity, bleach?)

Gene,
I find the dna candidates to test. Suzanne Hallstrom contacts the candidates to see whether they'll participate in our study, and handles all the dna analysis part. I am limited in my basic dna knowledge, and don't know how long dna in blood remains traceable under ideal conditions. I think I've stated before that I'm not a geneticist. Surely we have someone at the Symposium who is?

What do you think?

I think perhaps I should try to find out how many sheet relics there are before assuming the Charles Skelderman piece was the only one taken. As for the possibles at the Chicago History museum I've seen their list before, and there are others besides those, some of whom have contacted Suzanne, but only one has gone forward with testing, and that was the piece from Mary Todd Lincoln's chair. The owner had thought it was Abe's blood, but it was Rathbone's.

We remain hopeful, going forward, that we'll get a chance to get Abe's dna tested. The hair sample at the Chicago History museum may be a useful relic to test in that regard. Too early to make any promises.
