General description

Each vial contains 1 μmole of purified desmosine.


Desmosine chloride is often used in assays for free or urinary desmosine as markers for disease states characterized by elastin degradation (e.g., emphysema). Elastin degradation has shown strong correlation with vascular calcification, and pretreatment with aluminum ions can inhibit the binding of matrix metalloproteinase (MMP) to elastin.
Assays for free or urinary desmosine are often used as markers for disease states characterized by elastin degradation (e.g., emphysema). Conversely, excessive levels of incorporated desmosine are indicators of fibrotic conditions (e.g., cirrhosis).

Biochem/physiol Actions

Desmosine is a polyfunctional amino acid that forms cross-links in mature elastin.


Extremely hygroscopic

An enhanced proteolysis of lung interstitium is key event in the pathogenesis of emphysema, a major constituent of chronic obstructive pulmonary disease. To assess whether urinary desmosine and/or hydroxyproline may be used as a marker of lung destruction we studied...

Calcification of elastin occurs in many pathological cardiovascular diseases including atherosclerosis. We have previously shown that purified elastin when subdermally implanted in rats undergoes severe calcification and aluminum chloride (AlCl(3)) pretreatment of elastin inhibits calcification. In the present study we...

Elastin calcification is a widespread feature of vascular pathology, and circumstantial evidence exists for a correlation between elastin degradation and calcification. We hypothesized that matrix metalloproteinase (MMP)-mediated vascular remodeling plays a significant role in elastin calcification. In the present studies...
