  • Patent number: 10238985
    Abstract: The present application relates to a hard-core and soft-shell toy building blocks set, comprising polycarbonate matrix having tenon on its top and several mortise holes on its bottom; the outside surface of said polycarbonate matrix is cladded with thermoplastic polyurethane elastomer rubber layer. Said hard-core and soft-shell toy building blocks set provided in the this embodiment unitizes both conventional hard and soft kinds of cordwood toy by cladding thermoplastic polyurethane elastomer rubber layer on the outside surface of polycarbonate matrix, learning strong points from both to overcome their weaknesses, it produces high bounce ability, high resistance to wearing, bending, high temperature and oxidation, particularly, it is well worth mentioning that the new product is nonpoisonous, non-absorption of water and oil, no harm to health of children.

  • Patent number: 7906629
    Abstract: Activated haptens useful for generating immunogens to HIV protease inhibitors, immunogens useful for producing antibodies to HIV protease inhibitors, and antibodies and labeled conjugates useful in immunoassays for the HIV protease inhibitor saquinavir. The novel haptens feature an activated functionality at the central, non-terminal hydroxyl group. Also described are monoclonal antibodies specific for saquinavir having less than 10% cross-reactivity with lopinavir, nelfinavir, amprenavir, ritonavir, and indinavir, and a murine hybridoma producing said antibodies.
