  • Publication number: 20140220042
    Abstract: The invention pertains to the generation and utility of antibodies that can bind effectively to C?mX domain on membrane-bound IgE (mIgE) expressed on the surface of human B lymphocytes. The C?mX domain of 52 amino acid residues, located between the CH4 domain and the C-terminal membrane-anchor peptide on human membrane-bound epsilon chain, had been suggested as an antigenic site for immunological targeting of B cells expressing mIgE. Previous reported monoclonal antibodies, including a20, which bind to RADWPGPP (SEQ ID NO:1) peptide at the C-terminal of C?mX, have now been found to bind poorly to mIgE on human B cells. We have discovered that only monoclonal antibodies specific for certain segments, such as GLAGGSAQSQRAPDRVL (SEQ ID NO:2) and HSGQQQGLPRAAGGSVPHPR (SEQ ID NO:3), of C?mX can bind effectively to mIgE on human B cells and hence have the utility for targeting those B cells for the treatment of diseases mediated by IgE.

  • Publication number: 20090166831
    Abstract: This invention provides a sensor semiconductor package and a method for fabricating the same. The method includes: mounting on a substrate a sensor chip having a sensor area; electrically connecting the sensor chip and the substrate by means of bonding wires; forming on a transparent member an adhesive layer with an opening corresponding in position to the sensor area; and mounting the transparent member on the substrate via the adhesive layer while heating the substrate, such that the adhesive layer melts, to thereby encapsulate the periphery of the sensor chip and the bonding wires while exposing the sensor area from the adhesive layer. Thus, the sensor area is sealed by the transparent member cooperative with the adhesive layer, making the sensor semiconductor package thus-obtained dam-free, light, thin, and compact, and incurs low process costs. Also, the product reliability is enhanced since the bonding wires are encapsulated by the adhesive layer without severing concern.

  • Publication number: 20080303111
    Abstract: The invention discloses a sensor package and a method for fabricating the same. The sensor package includes: a substrate with an opening; a sensor chip disposed in the opening and electrically connected to the substrate; an encapsulant filling spacing between the sensor chip and the opening so as to secure the sensor chip to the substrate; and a transparent cover attached to the substrate via an adhesive layer, wherein the adhesive layer covers the sensor chip and bonding wires and is formed with an opening for exposing sensor region of the sensor chip. Securing the sensor chip in the opening of the substrate reduces the height of the sensor package, and meanwhile the process cost is reduced by eliminating the need of formation of conductive bumps on the sensor chip or the transparent cover and eliminating the need of specially designed substrate.
