Dear all,
I am having trouble extracting DNA from some 1000yr bone samples that have
been treated (20 yrs ago) with Paraloid B72 (ethy methacrylate co-polymer,
also known as Acryloid B72).
Does anyone have any experience with this?
In the last Conference on Ancient DNA and Assoc. Biomolecules, Helen
Donoghue suggested that I tried PTB, which would disrupt any cross-link, in
the case that was the problem. I think it is worth trying it, but cannot find this
product.
Does anyone know where this 'strange chemical' can be purchased?
And does anyone have other suggestions/ideas?
Thank you very much,
Cecilia Sosa
