An apparatus for carrying sound production components is disclosed, comprising a rigid frame including vertically interspaced first, second, and third surfaces. Each of the first surface, second surface, and third surface releasably engage with a plurality of sound production components. A first wing and a second wing are pivotally mounted to the third surface to releasably engage with at least one of the plurality of sound production components. A bag receives the rigid frame in a folded configuration and encloses the rigid frame and the plurality of sound production components.

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

A foldable shelving unit includes one or more foldable shelves positioned between first and second frame members. A slide rail pivotably couples between the foldable shelves. A stop is fixed to the slide rail and a slide locking mechanism is slidable along the slide rail. The slide locking mechanism includes a latch to latch to the stop to lock the shelving unit in an unfolded configuration and unlatch to slide the slider along the slide rail away from the stop to fold the shelving unit into a folded configuration.

Foldable storage compartment having front and rear panels that are traversable closer to or further away from each other is disclosed. Left and right side collapsible panels may be attached to the front and rear panels. The shelves of the foldable storage compartment may be interlinked with each other by way of a vertical linkage rod and connected to the front panel with a front panel linkage so that traversal of the front and rear panels closer to or further away from each other will also collapse and erect the shelves simultaneously.

A system of racks comprising of at least two racks that can be nested together when they are not in use thereby minimizing the space required for their collective storage. Each rack is comprised of a frame having two or more frame elements linked together by at least one Z-shaped bracket. Each frame element is comprised of two vertical support members linked by a plurality of tray holders at spaced apart distances along the interior side(s) of the vertical support members. The plurality of tray holders on each of the frame elements linked by a Z-shaped bracket are substantially aligned in the vertical direction thereby forming a set of pairs of tray holders. Each pair of tray holders is configured to receive and support the placement of trays. The trays comprise of a flat base portion with upstanding side edges which may be welded to a wire element to reduce crevices where debris and contaminants may otherwise be trapped and to assist with cleaning of the trays. When the racks are not in use, the trays are removed allowing the racks to nest together along their Z-shaped bracket.

The present invention relates to stabilization of RNA, in particular mRNA, and an increase in mRNA translation. The present invention particularly relates to a modification of RNA, in particular in vitro-transcribed RNA, resulting in increased transcript stability and/or translation efficiency. According to the invention, it was demonstrated that certain sequences in the 3′-untranslated region (UTR) of an RNA molecule improve stability and translation efficiency.
