  • Publication number: 20210300964
    Abstract: Methods for the production of high purity recombinant protein such as monoclonal antibodies (mAb) using disulfide bond re-oxidation are provided. In particular, the present disclosure provides methods for converting partial molecules (e.g., antibody fragments) to full molecules (e.g., full antibodies) comprising admixing a starting solution comprising the partial molecules with a redox buffer comprising a redox pair which comprises at least one thiol reducing agent (e.g., cysteine) and at least one thiol oxidizing agent (e.g., cystine), wherein the redox buffer re-oxidizes the partial molecules to full molecules. The disclosed methods can be used, e.g., to prevent or mitigate the formation of partial molecules during protein purification, or to reprocess or rescue a solution comprising partial molecules (e.g., a partially degraded pharmaceutical formulation).

  • Publication number: 20180341886
    Abstract: A decision support engine for dynamically scheduling interactions between a first party and a second party includes: a processor and a memory coupled to the processor. The memory having stored therein instructions, that, when executed by the processor, cause the processor to: receive an inputted target file including a target number of first channel interactions and a target number of second channel interactions; receive an inputted date period; receive calendar data of the first party; distribute the first and second channel interactions over the date period; compare the date of a first one of the assigned first channel interactions with the corresponding date of the first party's calendar data, and when the calendar data indicates there is a conflict, shifting the first one of the assigned first channel interactions by one day and comparing the new date with the corresponding date of calendar data.

  • Patent number: 9951606
    Abstract: A method and apparatus for directional drilling using mechanical wave detectors and a drill string having a drill bit at a drill bit end of the drill string. During an underground drilling operation in an underground formation, a mechanical wave signal is transmitted using a mechanical wave transmitter carried at the drill bit end of the drill string. The mechanical wave signal is received by an array of mechanical wave receivers at a ground surface above the underground formation. The received mechanical wave signals are processed to determine at least the location of the drill bit in the underground formation. The position and direction of travel data is communicated to a drilling control unit.
