Chemically isolated preparations of acid and normal Mg2+, Ca2+-, and guanidine+ salts of cartilage proteoglycan aggregates were investigated by electron microscopy. Some differences between acid and normal salts depend on the amount, valency and distribution of basic ion as well as between carboxyl and sulphate groups.
