Title: Unitized railcar brake equipment
Inventor: HART JAMES E
IPC: B60T17/00
Filed: 2002-06-27
Abstract: A unitized railcar brake equipment can have a relatively small integrated air supply and can be controlled electronically.

Patent CA-2405332-A1 (CA)
Title: Fluorescence assay for gamma-secretase activity and inhibitors
Inventor: LEWIS MARTIN
IPC: C12N5/071
Filed: 2001-03-30
Abstract: The present invention provides an isolated, functionally-active protein that catalyzes cleavage of a gamma-secretase substrate. The functional activity of the isolated protein suggests that the isolated protein includes gamma-secretase. In one embodiment, the isolated gamma-secretase protein is associated with PS1. The present invention also relates to homogeneous methods for monitoring cleavage of .beta.-amyloid precursor protein (.beta.APP) by gamma-secretase, wherein the steps of isolating and retrieving cleavage products have been eliminated. Cleavage can be detected by binding a pair of fluorescent adducts to the gamma-cleaved .beta.APP fragment. Preferably, a first fluorescent adduct binds to the carboxy-terminal end of the gamma-cleaved .beta.APP fragment, with substantially no cross-reactivity to uncleaved .beta.APP or to other types of gamma-cleaved .beta.APP fragments, while a second fluorescent adduct binds to a portion within the amino-terminal region on the gamma-cleaved .beta.APP fragment. Detection of binding to the gamma-cleaved .beta.APP fragment is determined by monitoring the fluorescent energy transfer between the adducts.
