摘要: Described herein are methods for the efficient production of antibodies and other multimeric protein complexes (collectively referred to herein as heteromultimeric proteins) capable of specifically binding to more than one target. The targets may be, for example, different epitopes on a single molecule or located on different molecules. The methods combine efficient, high gene expression level, appropriate assembly, and ease of purification for the heteromultimeric proteins. The invention also provides methods of using these heteromultimeric proteins, and compositions, kits and articles of manufacture comprising these antibodies.

摘要: Methods for the controllable expression in high yields of heterologous proteins under the control of a modified tryptophan promoter-operator system are disclosed. The system employed involves sequential resort to tryptophan repression and derepression, as well as deletion of an attenuator function native to the tryptophan operon. Means are also disclosed for effecting deletions at any given point within a gene fragment and for the ready identification of transformant bacteria via triple ligation procedures.

摘要: The instant invention discloses the unexpected result that mutant signal sequences with reduced translational strength provided essentially complete processing and high levels of expression of a polypeptide of interest as compared to wild type signal sequences, and that many mammalian polypeptides require a narrow range of translation levels to achieve maximum secretion. A set of signal sequence vectors provides a range of translational strengths for optimizing expression of a polypeptide of interest.
