C. elegans Chemical Response Assay
Description
Chemotaxis is the movement of cells or organisms in response to a chemical signal. In nature, it helps organisms find food and move away from harmful substances. It also matters at the cellular level. For example, sperm use chemotaxis to move toward an egg before fertilization.
In the lab, chemot...

Transcript
The movement of a cell or organism in response to a chemical stimulus is a behavior called chemotaxis. In this video, we will learn how to perform a chemotaxis assay using the nematode, C. elegans. We will also discuss how chemotaxis assays in C. elegans are applied to study learning and memory, olfactory ad...
