Gram staining, also known as Gram's method, is a method of differentiating bacterial species into two large groups (Gram positive and Gram negative).
In vitro bacterial culture
The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.

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.
Bacillus gram positive stain under the microscope view. Bacillus is rod-shaped 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.
