    摘要: Compositions, methods, and kits for detecting and monitoring post-translational modification activities, including kinase or phosphatase activities, are described. The compositions typically include a peptide, a first detectable moiety, a first binding member, and a protease cleavage site. Modification of a composition by a post-translational modification enzyme, such as a kinase or phosphatase, alters the proteolytic sensitivity of the peptide, resulting in a change of a detectable property of the composition when it is associated noncovalently with a probe composition that includes a second binding member and a second detectable moiety. Panel assays for determining substrates or modulators of enzymatic activities are also described.

    摘要: The present invention relates to biosensors. In some embodiments, the biosensors are modified ligand binding molecules. In some embodiments, the modified ligand binding molecule is a phosphate binding protein (PBP). In some embodiments, the modified ligand binding molecules are labeled to be capable of RET, e.g., comprising a donor and acceptor moiety. In some embodiments of the invention, there is a detectable change in RET (e.g., FRET) when the modified ligand binding molecule binds and/or releases the ligand (e.g., phosphate). The invention also provides related methods, reactions and assays.

    摘要: Systems, methods, circuits and/or devices for generating high repetition rate ultra-short pulses are described. As one of many examples, an optical pulse generating laser system is described that produces mode-locked optical pulses. The laser system incorporates an optical pulse generation device that includes two optical loops coupled via a beam splitter. In addition, the optical pulse generation device includes an optical gain medium that is associated with the first optical loop, and a saturable element that is disposed in either the first optical loop or the second optical loop. The saturable element is operable to modulate a group of optical pulses propagating in at least one of the first optical loop and the second optical loop to create a group of substantially regular modulated pulses.
