3D cartoon and Gaussian surface models, PDB 2j0D, white background.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway. Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).
A model of a nucleosome. Isolated on black.
Antimicrobial susceptibility testing in petri dish. Microbiologist check Antibiotic resistance of bacteria
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.
Backgrounds of Bacteria and Mold under the microscope in Lab.
plant Stem-Collenchyma C.S. under light mircoscope with white background
3D cartoon and Gaussian surface models, chain id color scheme, PDB 3omv, white background
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway. Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
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.
Particles, medical concept
Transmission electron microscope micrographs showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
Slice of natural crystal for patterns and textures use with high resolution.
Protein enzymes fold into their structure to fulfill their function - 3d illustration
plant rape flower cross section under light mircoscope with white background
3D cartoon and Gaussian surface models, PDB 6p8e, white background
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
Gram staining, also known as Gram's method, is a method of differentiating bacterial species into two large groups (Gram positive and Gram negative).
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
brown fat cell also called brown adipose tissue side to side with white fat cell 3d rendering
Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Liver Fluke Section under light microscope with white background
The RNA dependent RNA polymerase (RdRP, blue) of catalyzes the replication of the viral RNA from an RNA template (violet) producing a complementary RNA strand (orange) by attachment of single ribonucleosides. Source: PDB entry 7l1f.

Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
Photomicrograph of newly hatched freshwater leech. Note multiple eyes at head and second attachment sucker at tail. Body length approx. 3 mm. Live specimen. Wet mount, 5X objective, transmitted brightfield illumination.
