Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Blood sampling tube for HbA1c analysis.
Abstract technological design of an artificial molecular structure in many colors. Horizontal wide composition.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

Fat cells contain a large lipid droplet (yellow), a nucleus (red) and cell organelles located in the periphery.
Labeled for Ascariasis detection through stool examination, this test tube is used to diagnose Ascariasis, a disease caused by the Ascaris lumbricoides worm, which is one of the most common worm infections.
3d rendering of lipid monolayer is a type of cell membrane in which the lipids are arranged in a single layer, rather than the typical bilayer. Several Archaea have a lipid monolayer

Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata.
