Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: An input device includes a control surface for a color correction system. The control surface includes a housing with an upwardly facing control panel. The control panel has a proximal edge which is nearest a user and a distal edge that is furthest from a user in normal use. The control panel includes a plurality of controls. The plurality of controls includes: a plurality of trackballs, wherein each trackball comprises a ball and a control ring, said ball cooperating with at least one encoder to generate a multi-dimensional control signal based on motion of the ball, and said control ring cooperating with at least one encoder to generate a one dimensional control signal based on the rotational motion of the ring, wherein the ball of said trackball is mounted concentrically with said control ring; a plurality of control buttons; and a plurality of knobs coupled to respective rotary encoders.

Abstract: The present invention provides fluorescent cyanine dye-based nucleotide analogues, in which the cyanine dye is coupled to the ?-phosphate group of a nucleoside triphosphate. Preferred embodiments of the invention are directed to fluorescent cyanine dye-based GTP analogues which may be employed in an homogeneous FRET-based assay to measure the binding of guanine nucleotides to GPCR polypeptides, or alternatively, to measure the effect of an exogenous ligand on GPCR protein binding.

Abstract: A cyanine dye having the structure has an overall positive charge greater than +1, by virtue of the presence of one to five positively charged N or P or S atoms, and also has a reactive or functional group by which it may be linked to a biomolecule or a solid surface.

Abstract: The present invention discloses a method of separating or distinguishing carbohydrate substances. More particularly the method includes using fluorescent labeling reagents which have a positive charge when bound to a carbohydrate, involves separating the labeled carbohydrate substances, such as by performing electrophoresis to cause differential migration of different labeled carbohydrate substances, or by isoelectric focusing in a pH gradient. The fluorescent labeling reagents are preferably cyanine dyes.
