| 20110245474 | METHODS FOR G-CSF PRODUCTION IN A PSEUDOMONAS HOST CELL - The present invention relates to the field of recombinant protein production in bacterial hosts. It further relates to expression of soluble, active recombinant protein by using secretion signals to direct the protein to the periplasmic space of a bacterial cell. In particular, the present invention relates to a production process for obtaining soluble hG-CSF protein from a bacterial host. | 10-06-2011 |
| 20110217784 | METHOD FOR PRODUCING SOLUBLE RECOMBINANT INTERFERON PROTEIN WITHOUT DENATURING - The present invention relates to the field of recombinant protein production in bacterial hosts. It further relates to extraction of soluble, active recombinant protein from an insoluble fraction without the use of denaturation and without the need for a refolding step. In particular, the present invention relates to a production process for obtaining high levels a soluble recombinant Type 1 interferon protein from a bacterial host. | 09-08-2011 |
| 20110111977 | HIGH THROUGHPUT SCREENING METHOD AND USE THEREOF TO IDENTIFY A PRODUCTION PLATFORM FOR A MULTIFUNCTIONAL BINDING PROTEIN - Methods of identifying and expressing an antibody variant are disclosed wherein the method comprises identifying a binding region in an antibody, fusing the binding region to a plurality of scaffolds of antibody constant regions to obtain antibody fragment variants, expressing the antibody fragment variants in organisms to form constructs and expressing the constructs carried by the organisms to form induced cultures, wherein the organisms are expressed in HTP mode. | 05-12-2011 |
| 20110020868 | BACTERIAL LEADER SEQUENCES FOR INCREASED EXPRESSION - Compositions and methods for improving expression and/or secretion of a polypeptide of interest in a host cell are provided. Compositions including a coding sequence for a bacterial secretion signal peptide are provided. The compositions of the invention are useful for increasing accumulation of properly processed proteins in the periplasmic space of a host cell, or for increasing secretion of properly processed proteins. In particular, isolated secretion signal peptide-encoding nucleic acid molecules are provided. Additionally, amino acid sequences corresponding to the nucleic acid molecules are encompassed. The present invention provides for isolated nucleic acid molecules including nucleotide sequences encoding the amino acid sequences shown in SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24, and the nucleotide sequences set forth in SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, and 23, as well as variants and fragments thereof. | 01-27-2011 |
