Enzymatic identification of soluble GAG

Treatment	GAG Fraction remaining
	Kidney	Liver	Brain
	−/−	−/−	−/−	+/−
Mock-treated	1.0	1.0	1.0	1.0
Heparan sulfate lyase I	0.2	0.4–0.7	—	—
Heparan sulfate lyase II	0.1	0.2	0.9–1.0	0.9–1.0
Chondroitin ABC lyase	1.0	1.0	0.2	0.2
Chondroitin AC lyase	—	—	0.1–0.2	0.1

The numbers represent the fraction of GAG remaining in each extract after digestion with lyase, relative to the amount remaining in the mock-treated extract.
