CS-4 and CS-6 ratios and corresponding molecular weight (MW) determined for CS from bovine and piscine sources, as previously determined.

	Bovine	P. glauca	R. clavata	S. canicula
Ratio 1* (CS-4)	0.8 ± 0.2	0.27 ± 0.07	0.46 ± 0.09	0.20 ± 0.07
Ratio 2* (CS-6)	0.22 ± 0.01	0.96 ± 0.09	0.67 ± 0.03	0.40 ± 0.03
MW**	≈ 20 kDa	60 kDa	44 kDa	43–45 kDa

Index for CS-4 prevalence: Ratio 1= 0.8–1.0 and Ratio 2= 0.12–0.26; Index for CS-6 prevalence: Ratio 1 = 0.2–0.4 and Ratio 2= 0.8–1.0. References: * [22] ** [19].
