Figure 3From: SP-A binds alpha1-antitrypsin in vitro and reduces the association rate constant for neutrophil elastaseEffects of calcium removal and sugar addition on K ass M-1sec-1. Inhibition of HNE by α1-AT (7.5 nM), alone or coupled with 7.5 nM SP-A: (1) α1-AT alone, (2) α1-AT plus SP-A, (3) α1-AT plus SP-A with 5 mM EDTA and (4) α1-AT plus SP-A with 1 M MNOCH3. (Data are means ± SD of experiments performed in triplicate).Back to article page
