  • Water soluble G-protein coupled receptor
    Patent number: 9670264
    Abstract: Described herein are recombinant integral membrane proteins having multiple transmembrane domains that have been engineered to be less hydrophobic, through alteration of the amino acid sequence of the native protein, but retain the ability to bind their natural ligand. The decreased hydrophobicity of the described proteins makes them more water soluble than the native protein, which allows the described proteins to be expressed in bacteria in large quantities and isolated in the absence of membranes, all while retaining the ability to interact with known ligands.

  • ORAL CARE IMPLEMENT
    Publication number: 20170150808
    Abstract: An oral care implement (100) in one embodiment includes an elongated body (101) comprising a head portion (110) supporting plurality of tooth cleaning elements (111) and a handle portion (120) defining an outer surface (127). A grip control component (130) is disposed on the handle portion (120) and includes a pair of transversely spaced apart control surfaces (132) separated by a longitudinally extending channel (133). The control surfaces (132) are elevated above the outer surface (127) of the handle portion (120) and positioned to engage a user's thumb. The control component (130) is operable to tilt the head portion (110) at an upward or downward angle relative to a vertical plane of a user's teeth when the control component (130) is grasped between the user's thumb and forefinger for producing a proper brushing angle at the gum line.
