From: Human placental proteomics and exon variant studies link AAT/SERPINA1 with spontaneous preterm birth
Confocal microscopy images of human placenta expressing endogenous AAT, fibronectin, vitronectin, and collagen IV. Colocalization fluorescence image of AAT (green) and fibronectin (red) (top row), AAT (green) and vitronectin (red) (middle row), and AAT (green) and collagen IV (red) (bottom row). Middle columns are separate green channel, red channel, and brightfield images, which are shown merged in left column. Panels in right column show negative controls treated the same way as samples but with primary antibody omitted. Objective lens: HC PL APO CS2 × 20/0.75 DRY. Scale bar: 10 μm
