Glycogen v tRNA and OLD BONES

[Scrimshaw, Brian J]

Can someone in netland explain the relative virtues of glycogen
and tRNA as a carrier? Are they just as good as each other for
sticking to DNA?

I'm trying to extract DNA from old bones and have been using
glycogen as a carrier, with little luck, it may just be the DNA
in the bones is too degraded or a protocol problem. I had no luck
with silica and am trying a proteinase K approach with
concentration in a microcon 30 after addition of glycogen, any
advice appreciated.
