I don't think you can do the jurrasic park thing of blood in amber. But, the dna could leave enough residue that you could possibly interpret the data to reconstruct the base pairs data and then if you had the technical skill, to recreate the base pair sequence, one pair at a time.
I doubt any DNA remains, it's probably completely shredded. Instead I hope some fragments of protein remain since it's a much tougher molecule. Some tests Dr. Schweitzer did suggest fragments of collagen may remain.
