  • Publication number: 20210206810
    Abstract: A detection of optimal genetic recombinants used to prepare target proteins, with assessment of their target-specific “upstream” productivity, genetic stability and means to optimize target protein “downstream” purification using customizable fluorescent tags. A scarless removable protein fusion makes it possible to identify recombinants of Pichia pastoris with optimal performance in heterologous protein production.

  • Publication number: 20060280011
    Abstract: Voltage coupling/decoupling devices are provided within DRAM devices for improving the bias sensing of sense amplifiers and thus the refresh performance. The voltage coupling/decoupling devices couple or decouple bias voltage from corresponding digit lines coupled to the sense amplifiers. By coupling and decoupling voltage from the digit lines, the time interval between refresh operations can be increased.
