STOCK IMAGE CATALOGUE

An illustration of a brown mouse with pink ears, pink paws, and a pink tail, viewed from a color-oblique angle.
Four illustrations of a mouse in lateral view, each with a different shading pattern or outline style.
Illustration of three fruit flies, showing top, side, and top-down views with data labels for males and females.
A collection of diagrams showing different mouse behavior tests, including water maze, Y-maze, pole, open field, and grip strength tests, with some tests featuring a mouse navigating through various mazes or gripping a wire.
Illustrations of two laboratory tests involving rats. The left shows a pole test with a rat hanging from a vertical pole, and the right shows a grip strength test with a rat holding a horizontal bar while a gloved hand pulls on its tail.
Diagram showing three mouse brains at different angles, each with labeled IDs and titles, and arrows pointing to cross-sectional views of their brains.
Three diagram slices of a mouse brain, labeled with IDs 00019, 00020, and 00021, showing different cross-sections in a coronal view with a pink and beige color scheme.
Diagram of four types of brain cells: top left, ramified microglia with many branching extensions; top right, reactive microglia with fewer and thicker extensions; bottom left, nonreactive astrocyte with star-shaped structure and thin extensions; bottom right, reactive astrocyte with a more expanded structure and thicker extensions. Each cell type is labeled with ID and title.
Illustration of three cell types: a generic cell, a generic cell with mitochondria, and a neuron with myelin, each labeled with ID numbers and titles.
Diagram of mouse anatomy with labeled illustrations of the mouse stomach and two views of the mouse brain, one superior and one lateral.
Diagram of a gut-brain Parkinson's disease model and laser capture microscopy process. The gut-brain model shows a mouse with an injection of alpha-synuclein preformed fibrils into the gut, which interacts with the vagus nerve. The microscopy setup depicts a laser capturing a tissue sample from nervous tissue using laser capture microscopy.
Diagram depicting an experiment involving mice with injections, microglia culture, and molecular analysis with Western blot and PCR methods.
Diagram of two experimental procedures involving microglia and astrocytes. The left side shows pretreatment of primary microglia with CMPD067, followed by lysate and Western blot analysis. The right side shows pretreatment of primary microglia with CMPD067, induction of primary astrocytes with MCM, and subsequent analysis with qPCR, Western blot, and immunocytochemistry.
Diagram showing a scientific experiment workflow involving protein modification, cell transfection, and immune cell activation. The process includes protein cleavage, purification, and cell culture steps leading to immunological assays.
Diagram showing experimental procedures involving primary microglia, astrocyte, and cortical neurons, with details on treatments using alpha-synuclein pre-formed fibrils (PFF) and aggregates, and analyses like Western blot, tissue lysate, TUBE pull-down, and detection of NF-kB and MAPK signaling.
