Figure 1From: SP-A binds alpha1-antitrypsin in vitro and reduces the association rate constant for neutrophil elastaseSDS-PAGE under reducing conditions. A: α1-AT; B: SP-A. Lane 1: molecular weights; lane 2: native protein; lane 3: deglycosylated protein. The two bands in gel B, lanes 2 and 3 correspond to dimers (57 and 50 kDa, respectively) and monomers (33 and 27 kDa, respectively) of SP-A.Back to article page
