Rhodamine-phalloidin (actin stain) in the trunk of a 24 hr zebrafish embryo. Images made available by Mark Cooper thru The Zebrafish A Living Laboratory.

3 hr zebrafish embryo labeled with anti-phosphotyrosine antibody (green) and anti-phosphoserine (red). Images made available by Mark Cooper thru The Zebrafish A Living Laboratory.

Stereo pair of an embedment-free section of a detergent-extracted 8-cell embryo reveals the cytoskeletal interior in greater detail than is afforded in resin-embedded sections. The specimen is viewed...

Cultured chicken embryonic cardiomyocyte fixed and stained for alpha-actinin using a monoclonal antibody and Alexa-546 as a secondary fluorescent antibody. Imaged by widefield epifluorescence on a Zei...

Transmission electron micrograph of a section through a 3-day old chick embryo obtained from an egg that was maintained in a cold room for 24 hrs. Ribosomes have crystallized both in the cytoplasm an...

Cultured chicken embryonic cardiomyocyte transfected with GFP control vector in the nucleus, stained with alpha-actinin at the Z-lines in red and Tropomodulin1 (at the pointed ends of the actin filame...

Transmission electron micrograph of a negatively stained preparation of ribosomes isolated from a 3-day old chick embryo that was maintained in a cold room for 24 hrs. The ribosome crystals seen in ...

Zebrafish embryo undergoing cytokinesis. The embryo is expressing fixed EMTB-3GFP (microtubules-marker, green) and is labeled with phalloidin (actin marker, red) and Hoechst (DNA marker, blue). Note...
