Heterologous immuno-localization of the hPAG-L/pep proteins within sections of human term placenta identified with recombinant anti-porcine PAG (anti-Rec pPAG2) polyclonals (A–H), visualized by goat anti-rabbit IgG-conjugated with Alexa 488 fluorophore (green) among all nuclei stained by propidium iodide (red). Human placenta section—used as a negative control (NC; insert in H) with omitted polyvalent anti-pPAG-P polyclonals. The size bars are 50 µm (E–H and NC), 100 µm (A,C,D) and 200 µm (B). Abbreviations: arrowheads—syncytiotrophoblast; arrows—clusters of the syncytiotrophoblast nuclei; IS—intervillous space; CV—chorionic villi; SB—stratum basale; PS—placental septa; FC—fetal capillary; NC—negative control.
