Summary of kinetic data of heparin–piscidin interactions

The data with ± in parentheses are the standard deviations (S.D.) from global fitting of five injections using a 1:1 Langmuir model, with K_d = k_d/k_a. The experiments were repeated three times.

Interactions	ka (m−1 s−1)	kd (s−1)	Kd (m)
Heparin–P1	1300 × 104 (±4.7 × 102)	0.121 (±2 × 10−3)	9.31 × 10−6 (±5.1 ×10−7)
Heparin–P3	3.20 × 103 (±1.6 × 102)	0.150 (±3 × 10−3)	4.69 × 10−5 (±3.3 ×10−6)
