20090025813Water diverting device - This present invention provides a water diverting device. There is an inlet and two outlets in its inlet and outlet pipeline, and there is an upper sealing seat and a lower sealing seat respectively for the two outlets; the said water diverting device is provided with a water diverting switch that fits with the said sealing seats and used to switch over the two outlets. The said switch includes a sliding shaft and, fixed base, and there is a sliding through hole for the sliding shaft. The said switch is also provided with a retaining hook for holding the sliding shaft up and down direction. On the surface of the said sliding shaft, there are the first stop position and second stop position fitting with the hook part of the retaining hook, first unidirectional slide channel and second unidirectional slide channel. The said switch has a spring pushing the sliding shaft from head of the sliding shaft towards its tail. The said head of the sliding shaft is connected with a valve core, and the positions of the above-mentioned two sealing seats correspond with the travel of the valve core. For this present invention, water discharge direction can be changed over by only pressing a diverting switch, so this present invention is easy to operate and better complies with human habit of applying a force, with good sealing effect, excellent durability and long service life. In addition, this present invention has high operation reliability and its water diverting function is implemented without being affected by water pressure.01-29-2009

20090081701METHOD OF SELECTIVE PROTEIN ENRICHMENT AND ASSOCIATED APPLICATIONS - The present invention provides methods of selective enrichment of ligands present in a biological sample. One or a plurality of receptor carriers are used to capture ligands capable of binding to receptors immobilized on the surface of the receptor carriers. Receptor carriers bound with the ligands are separated from the remaining sample and the ligands are then eluted with a ligand elution solution to result in an enriched ligand sample. The enriched ligand sample may be used for further isolation of one or more ligands of interest, or for ligand profiling using 2-D gel electrophoresis coupled with mass spectrometry, for example. Such ligand profiling may have a number of applications, such as disease diagnosis, pathogen detection and drug screening.03-26-2009
20100062461MULTIPLEX DETECTION OF CELL SURFACE RECEPTORS OR IMMOBILIZED ANTIGENS - The present invention provides an antibody-based multiplex detection method for identifying one or more epitopes in one or more samples, the method comprising the steps of: (a) contacting each of the samples comprising the epitopes with one or more antibodies specific to the epitopes to be detected; (b) washing unbound antibodies away and eluting bound antibodies from the epitope carriers to provide separate antibody eluates; and (c) detecting and quantifying antibodies in the antibody eluates to generate separate profiles of antibodies for each of the samples. The epitopes to be detected can be located intracellularly, or present on the surface of cells or an artificial surface. In general, the epitopes are derived from protein, polypeptides with or without post-translational modification, carbohydrate, nucleic acid, or lipid.03-11-2010

20090148386ENZYME SUBSTRATE COMPRISING A FUNCTIONAL DYE AND ASSOCIATED TECHNOLOGY AND METHODS - Enzyme substrates and associated technology of the present invention are provided. An enzyme substrate of the invention may comprise a biologically functional fluorescent dye and an enzyme-specific substrate moiety attached in such a way that the functionality of the functional dye is diminished. An enzymatic reaction may cleave at least a portion of the substrate moiety from the enzyme substrate to provide a more functional product dye. This product dye may be nonfluorescent or weakly fluorescent, in general, and relatively fluorescent, in a particular condition, such as when bound to a partner biological molecule or an assembly of partner biological molecules. An enzyme substrate of the present invention may thus be useful in fluorescence detection, and/or in any of a variety of useful applications, such as the detection of enzymatic activity in a cell-free system or in a living cell, the screening of drugs, or the diagnosis of disease.06-11-2009
