Phase contrast image of serum arrested mouse L-1210 cells engaged in spontaneous apoptosis (programmed cell death) after nutrient depletion and acid hydrolysis. The image was taken at 40X, scanned, an...

Single slice through a single tilt tomogram of the Node of Ranvier from mouse sciatic nerve. This image has been downsampled from the raw data image which can be accessed using the link provided to th...

Single slice through a single tilt tomogram of the Node of Ranvier from mouse sciatic nerve prepared by high pressure freezing and freeze substitution of aldehyde fixed material. This image has been ...

During hippocampal neuron development in vitro, N-cadherin becomes selectively localized to excitatory synapses. This image shows immunolocalization of the NMDA receptor, which is postsynaptic. Other...

During hippocampal neuron development in vitro, N-cadherin becomes selectively localized to excitatory synapses. This image shows immunolocalization of N-cadherin (red), colocalized at synapses that a...

Transmission electron micrographs of serial sections of nerve cells illustration a dendrite. Note that this very early (1954) micrograph is primarily of historical interest since it pre-dates glutara...

Transmission electron micrograph of rat neuronal dendrite. Note that this very early (1954) micrograph is primarily of historical interest since it pre-dates glutaraldehye fixation which was introd...

Colorized scanning electron micrograph of Amarylis stigma (pink) with pollen grains (yellow) adhering to sticky glands on its surface. Some pollen tubes (olive green) carrying genetic material can be ...

Scanning electron micrograph showing Penta lanceolata unacetolyzed pollen. Compare this pollen to acetolyzed pollen images by the same contributor in the Library. This image is a ]higher magnificatio...

Time-lapse experiments showing deltorphin II (100 nM; a selective agonist)-induced internalization of delta-opioid receptor–enhanced GFP (DOR-EGFP; green) receptors expressed in HEK 293 cells. The C...
