  • Patent number: 11447560
    Abstract: Methods are provided for the synthesis and secretion of recombinant hetero-multimeric proteins in mating competent yeast. A first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are identified and then genetically crossed or fused. The resulting diploid strains are utilized to produce and secrete fully assembled and biologically functional hetero-multimeric protein.

  • Patent number: 10428301
    Abstract: Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.
