Different germs in the human intestines called microbiome,Bacteria Lactobacillus in human intestine,Beneficial healthy intestinal bacterium microflora,Gut bacteria
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange), that is aggregated to amyloid beta fibrils, which build up amyloid plaques.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
3D rendering of a biotinylated antibody linked to BODIPY molecules or bright green. This technique allows to visualize and track the antibody for targeted applications in medical research.
