Chemotactic and Ca2+ Responses of Sea Urchin Spermatozoon
This video shows the chemotaxis of a sea urchin sperm in Flou-4 (calcium dye) acquired using an Andor iXon EMCCD camera.
The Ca2+ drives the chemotactic response of the sperm along a photoinduced chemoattractant gradient. The images of the chemotactic and Ca2+ responses were captured using Nikon fluorescence microscopy.
