2. FIGURE 1
SDS-PAGE of pepsin-solubilized collagens from the human CL tissues during the menstrual cycle and early pregnancy; early luteal phase (lane 1), midluteal phase (lane 2), late luteal phase (lane 3), early pregnancy (lane 4), and type V collagen extracted from the human CL tissues (lane 5). Samples of heat-denatured collagen (5 μg, lanes 1–4; 1.0 μg, lane 5) were subjected to electrophoresis on a slab gel for 1 hour. After reduction in situ with β-mercaptoethanol for 30 minutes, electrophoresis was resumed for 1 hour.
