Inside protein molecule
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
A ball and stick model of Human Insulin. Isolated on black.
Biological protein and molecule, 3d rendering. 3D illustration.
Neuroendocrine carcinoma well differentiated (carcinoid) rectum with immunostain synaptophysin
3D cartoon and Gaussian surface models, chain id color scheme, PDB 7t3a, white background
Slice of natural crystal for patterns and textures use with high resolution.
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
DNA A-T Pair
Backgrounds of Bacteria and Mold under the microscope in Lab.
Models of an antibody broadly antagonistic to HIV.  A challenge in AIDS and HIV research is producing a vaccine which elicits antibodies effective against the many variations of HIV proteins.Isolated on white.
Biological protein and molecule, 3d rendering. 3D illustration.
Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
3D cartoon and Gaussian surface models. PDB 3kqg, chain id color scheme, white background.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).

Molecular model of lactose, a disaccharide sugar in milk.
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.
Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
