    Abstract: The present invention relates to all aspects of a guanine exchange factor (GEF), for example, a Rho-GEF, such as p115 Rho-GEF. A GEF modulates cell signaling pathways, both in in vitro and in vivo, by modulating the activity of a GTPase. By way of illustration, a p115 Rho-GEF, which modulates the activity of a Rho GTPase, is described. However, the present invention relates to other GEFs, especially other Rho-GEFs. The present invention particularly relates to an isolated p115 Rho-GEF polypeptide or fragments of it, a nucleic acid coding for p115 Rho-GEF or fragments of it, and derivatives of the polypeptide and nucleic acid. The invention also relates to methods of using such polypeptides, nucleic acids, or derivatives thereof, e.g., in therapeutics, diagnostics, and as research tools. Another aspect of the present invention involves antibodies and other ligands which recognize p115 Rho-GEF, regulators of p115 Rho-GEF activity, and methods of treating pathological conditions associated or related to a Rho GTPase.

    Abstract: An ion filter (10) for use in ion mobility spectrometry is described, together with a method for manufacturing the filter. The filter (10) is manufactured by removing portions from a monolithic structure to form a pair of electrodes which remain mechanically connected. The connecting portion (22) provides sufficient electrical impedance between the electrodes to effectively electrically separate the electrodes. The connecting portion may be doped or chemically modified to obtain a desired impedance, or this may be obtained through appropriate selection of physical dimensions.

    Abstract: A device having an air sampler, an electrospray apparatus, and a fluorescence excitation and detection system. The air sampler is capable of moving air suspected of containing a biological or chemical aerosol particle into a chamber. The electrospray apparatus is capable of spraying a charged solution into the chamber to coat the aerosol particles with a coating. The solution has a fluorescent-labeled biological or chemical marker capable of specific binding to the aerosol particle. The fluorescence system is capable of detecting fluorescence of the fluorescent label in the coating. A method of detecting the aerosol particle by: moving air suspected of containing the aerosol particle into a chamber; spraying the charged solution into the chamber with an electrospray apparatus, such that a coating of the solution is formed around the particle; exciting the fluorescent label; and detecting fluorescence of the fluorescent label.

    Abstract: An apparatus, system and method for detecting, identifying, classifying and/or quantifying chemical species in a gas flow using a micro-fabricated ion filter coupled to a system adapted to apply drive signals to the ion filter. Coupled to the ion filter is a system adapted to measure the output of the ion filter, which in turn is coupled to a system adapted to extract numerical parameters from the measured output of the ion filter to facilitate chemical detection, identification, classification and/or quantification of the gas flow.
