摘要:
An improved baculovirus vector capable of expressing genes in mammalian or insect host cells, and the uses thereof are disclosed. The improved baculovirus vector includes in sequence: a promoter; a first nucleic acid operably linked to the promoter for expressing a first protein in the mammalian or insect host cells; a chimera internal ribosomal entry site (IRES) comprising a portion of an enterovirus (EV) IRES sequence at least 90% identical to SEQ ID NO: 1 and a portion of a Rhopalosiphum padi virus (RhPV) IRES sequence at least 90% identical to SEQ ID NO: 2; and a second nucleic acid operable linked to the portion of the RhPV IRES sequence for expressing a second protein in the mammalian or insect host cells.

摘要:
The present invention discloses a method of manufacturing lightweight ceramics by mixing several raw materials such as a powdered glass material, a powdered alkali silicate, and a water-soluble polymer in a certain proportion to form a dry substrate, and then adding water to mold the substrate into a desired shape; after the water in the substrate is baked dry, heat the substrate until the ceramic is formed. The oxide and hydroxide in the alkali silicate are used to lower the softening point of the powdered glass material, and when the powdered glass material is in the semi fluid state, the air and crystal water brought by the alkali silicate will expand and form air bubbles due to the high temperature. In the meantime, the water-soluble polymer at the high temperature will also be converted into a gas which will escape and form close pores inside the finished goods, and pores with open passages on the surface of the finished goods, such that the finished goods will have the lightweight, insulating, refractory, and water-resisting features.
