Dense microspheres can be extracted and purified to substantial homogeneity from mammalian brain tissue and, used in the screening of therapies for potential effectiveness in impeding the formation of amyloid fibrils associated with Alzheimer's disease and other forms of cerebral amyloidosis. Compounds that at in-, tissue concentrations of 10 -5 M or less inhibit amyloid, formation in a test animal injected intracerebrally with dense microspheres are particularly useful in inhibiting treating cerebral amyloidosis.

Why it's free to use
- Filed February 26, 1990 and granted May 8, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 26, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 26, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
