[Expression 1]

k.sub.1′+k.sub.2′+k.sub.3′≤9.3 N/mm  (1)

[Expression 2]

0.55≤k.sub.1′/(k.sub.1′+k.sub.2′+k.sub.3′)  (2)

wherein k.sub.1′ is a value obtained by dividing an equilibrium coefficient k.sub.1 by a thickness of a test piece, and k.sub.2′ and k.sub.3′ are values obtained by dividing viscous coefficients k.sub.2 and k.sub.3 by the thickness of the test piece, respectively.

The subject matter disclosed herein is generally directed to methods and compositions for tagging cells of interest, tracking evolution of the tagged cells, and recovering the original tagged cells for further study. Specifically, cells are tagged with a DNA construct encoding a barcode sequence comprising a guide sequence. Barcoded cells can then be recovered using a reporter construct having CRISPR target sequences specific for the cell having a barcode of interest.

According to various embodiments, a glove is provided with improved hydration characteristics and low dermatitis potential. The glove comprises a substrate and a polymer system that coats a surface of the substrate. The polymer system comprises: a polyol, a botanical extract, an emollient agent, a silicone copolymer dispersion, a lubricant, and a surfactant. The substrate may be free of sulphur and accelerators. An example formulation of the polymer system may comprise glycerol, Aloe vera, a carnauba wax dispersion, dimethicone, a polyalkylene glycol (PAG), and polyoxyethylene (20) sorbitan monooleate. The polymer system may be applied to the\surface of the substrate by dipping the surface into a water-based dispersion of the polymer system, or spraying the water-based dispersion onto the interior surface. The polymer system may be blended into water at a total solids content of 0.8% to 1.2% w/w to form the water-based dispersion.

A semi transparent nitrile glove comprising nitrile latex, caustic alkali, accelerators, vulcanizing agents, stabilizer and antifoaming agent, wherein the nitrile latex is any one selected from either acrylonitrile butadiene copolymer or carboxylated acrylonitrile butadiene copolymer, wherein the caustic alkali is a combination of either potassium hydroxide and ammonia or sodium hydroxide and ammonia, wherein the accelerators are chemical compounds of dithiocarbamates, wherein the vulcanizing agents are selected from both ionic and covalent vulcanizing agents, wherein the stabilizer is any one of either sodium dodecylbenzene sulfonate or sodium dodecyl sulfate and wherein the antifoaming agent is any one from a group consisting of silicone based antifoam, non-silicone based antifoam, oil based antifoam and water based antifoam wherein the semi transparent glove is without pigment and without titanium dioxide.

A reusable glove for meat processing plants that is able to be easily donned and doffed, and worn over a liner. A thumb crotch is defined between first sides of the glove's index finger region and thumb region. An imaginary first plane extends generally along the index finger region's first side, beyond the thumb crotch, and through the thumb region. An imaginary second plane oriented at right angles to the first plane extends along a narrowest width of the glove's wrist region and intersects the first plane at an intersection region. An imaginary third plane oriented parallel to the first plane and at right angles to the second plane, passes through narrowest width of the wrist region, and intersects the side of the wrist region at a transition region. The transition region is located outwardly beyond the intersection region and vertically below the thumb crotch.

Provided is a dip molding emulsion including, at least: an elastomer that contains a (meth)acrylonitrile-derived structural unit, an unsaturated carboxylic acid-derived structural unit, and a butadiene-derived structural unit in a polymer main chain; an epoxy crosslinking agent; water; and a pH modifier, in which dip molding composition the elastomer contains the (meth)acrylonitrile-derived structural unit in an amount of 20% by weight to 40% by weight, the unsaturated carboxylic acid-derived structural unit in an amount of 1% by weight to 10% by weight, and the butadiene-derived structural unit in an amount of 50% by weight to 75% by weight, and the epoxy crosslinking agent includes an epoxy crosslinking agent containing an epoxy compound having three or more epoxy groups in one molecule and has a dissolution rate in water of 10% to 70% as determined by a specific measurement method.

The present invention relates to a disposable safety glove system featuring a plurality of layers of inter-nested gloves that are worn simultaneously by a user. The improved disposable glove system of the present invention allows a user to peel away the outermost layer of gloves to reveal a new and sterile set of gloves. The glove system also features a relatively thick wristband to support the plurality of glove layers, a tab that can be used to easily peel off the outermost glove layer once the same has been used and a new pair of gloves is desired, and a numbering system that alerts the user to how many glove layers remain in the glove stack.

A glove with an enhanced gripping textured surface is disclosed herein. In preferred embodiments, the glove contains a palm region adapted to cover the palm of a person's hand, a thumb region extending outwardly from the palm region, an index finger region disposed adjacent the thumb region, a middle finger region adjacent the index finger region, a ring finger region adjacent the middle finger region, and a little finger region adjacent the ring finger region with each region containing a textured surface. In preferred embodiments, the textured surface is formed by a plurality of dimensionally hierarchical structures superimposed in layers. The textured surface of the invention, when in contact with wet tissue, repels water at a first texture layer and traps tissue at a second texture layer, such that when in tissue contact, especially exudative tissue, tissue fixatively localizes to the glove surface.

Disclosed is a dip-formed article obtained by dip-molding a latex composition for dip-forming, which contains a crosslinking agent and a latex for dip-forming containing a copolymer composed of 40-80% by weight of conjugated diene monomer units (A) containing an isoprene unit, 20-45% by weight of ethylenically unsaturated nitrile monomer units (B), and 2-15% by weight of ethylenically unsaturated acid monomer units (C), and having a weight ratio of butadiene unit content to isoprene unit content that falls within the range of 60:40 to 100:0. Tear strength is at least 50 N/mm, tensile strength is at least 25 MPa, and oil swelling rate does not exceed 5%.

The invention relates to a glove having at least one gripping aid arranged at the periphery of the cuff, the surface of which gripping aid at least partially has patterning, especially knobs and/or grooves, wherein the glove at least two of the total five finger spaces which are adapted to the fingers of a hand also has a structured surface or patterning, respectively, especially knobs and/or grooves, essentially at the ends of each finger space opposite the cuff which are provided for intake of the fingertips.
