Inhibition constants for inhibition of chemokine activity by purified evasins

Inhibition constants are reported as pIC₅₀ values (−log₁₀ of the IC₅₀; in m) ±S.E. The corresponding IC₅₀ values (in nm) are in parentheses.

	MCP-1	MCP-2	Eotaxin-1	Eotaxin-2
RSA evasin-4	a	7.00 ± 0.2 (100)	6.65 ± 0.2 (220)	5.99 ± 0.1 (1000)
RPU-01	7.47 ± 0.3 (34)	6.68 ± 0.1 (210)	6.03 ± 0.3 (940)	a
ACA-01	a	7.07 ± 0.1 (84)	6.39 ± 0.2 (400)	a
IHO-01	b	b	6.20 ± 0.2 (630)	5.95 ± 0.2 (1100)

^a IC₅₀ >1 μm (pIC₅₀ + S.E. <6) or no inhibition detected.

^b Not determined.
