This paper deals with the mechanical properties of cytoplasmic extracts from Xenopus laevis (African tree from). Xenopus extract is a common system because it's relatively easy to crush the eggs and extract the cytoplasm and each egg contains everything needed for ~30 divisions. Because of how well used this system is, it's interesting to consider the mechanical properties. This egg extract is used as an example system to try to study cytoplasm mechanics in general. In the paper, conventional macroscopic rheological measurements are made as well as microscopic microrheological measurements.
