The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross ....Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross-linked and substantially insoluble macroscopic network of tropoelastin multimers. Our availability of tropoelastin and synthetic elastin now makes these studies possible.Read moreRead less
Biochemistry of tropoelastin and elastin: the molecular architecture of elastic fibre assembly. Elastin destruction drives the progression of emphysema, a major component of chronic obstructive pulmonary disease which is a major cause of death. Loss of elastin leads to profound blockage of arteries. If we are to treat these problems we need to know how to make and repair elastin. This research will enable us to discover how elastin is constructed and define its interacting partners. We will lear ....Biochemistry of tropoelastin and elastin: the molecular architecture of elastic fibre assembly. Elastin destruction drives the progression of emphysema, a major component of chronic obstructive pulmonary disease which is a major cause of death. Loss of elastin leads to profound blockage of arteries. If we are to treat these problems we need to know how to make and repair elastin. This research will enable us to discover how elastin is constructed and define its interacting partners. We will learn how to make tissue components found in parts of the body that expand and contract such as the arteries, lung and skin. We will learn about the molecular mechanisms of elastin assembly and cell interactions, which gives us the core molecular toolkit to repair elastin tissue.Read moreRead less
