Interaction of Sulfated LMWLs and Heparin with Thrombin Using PABA Probes^a

Ligand	KD(μM)b	ΔF MAX b
CDS03	3.33 ± 0.12	−1.16 ± 0.01
FDS03	5.95 ± 0.44	−1.20 ± 0.04
SDS03	3.36 ± 0.11	−1.07 ± 0.01
UFH	1.74 ± 0.21	−0.34 ± 0.01

^aK_D and ΔF_MAX values of LMWLs and heparin were measured as described in Experimental Procedures. PABA reversibly binds to the active site of thrombin.

^bError represents ±1 SE.
