  • Publication number: 20250040546
    Abstract: The present disclosure provides compositions and methods of inactivating a lipid enveloped virus in a product feedstream in a manufacturing process of a therapeutic protein using environmentally compatible detergents. The present disclosure provides a detergent mixture comprising two environmentally sustainable detergents: n-Octyl-?-D-Glucopyranoside (OG) and n-Dodecyl-?-D-Maltopyranoside (DDM). The performance of this OG:DDM detergent combination is superior to that of Lauryldimethylamine Oxide (LDAO), ECOSURF™ EH9, or Triton X-100 in the purification of therapeutic proteins such as abatacept and belatacept. OG:DDM combinations are highly effective for viral inactivation, while having essentially no impact on protein stability, protein charge distribution (e.g., sialic acid levels), impurity clearance, protein deamination, or protein oxidation. Accordingly, combinations of OG and DDM can be used as substitutes of Triton X-100 for viral inactivation steps in the production of biologics.

  • Publication number: 20250034584
    Abstract: A genetically engineered land plant that expresses a protein that has homology to a plant invertase inhibitor and/or a pectin methylesterase inhibitor and that increases seed yield with increased expression (“an ISY protein”) is disclosed. The plant comprises a modified gene for the ISY protein. The ISY protein comprises one or more of an ISY protein of Camelina sativa comprising SEQ ID NO: 2 or a fragment, Camelina sativa homolog, or ortholog thereof. The modified gene comprises a promoter and a nucleic acid sequence encoding the ISY protein. The promoter is non-cognate with respect to the nucleic acid sequence encoding the ISY protein. The modified gene is configured such that transcription of the nucleic acid sequence is initiated from the promoter and results in expression of the ISY protein. A genetically engineered land plant that expresses an RNA that increases seed yield with increased expression also is disclosed.

  • Publication number: 20230257759
    Abstract: A genetically modified plant that exhibits an increase in seed yield relative to a progenitor plant is provided. The genetically modified plant includes: (a) a first biotin attachment domain-containing (badc) gene, occurring in its natural position within the genome and being homozygous for a wild-type allele: (b) a second badc gene, occurring in its natural position within the genome and being homozygous for a mutant allele; (c) one or more homologs of the first badc gene, each occurring in its natural position within the genome and being homozygous for a wild-type allele; and (d) one or more homologs of the second badc gene, each occurring in its natural position within the genome, and at least one being homozygous for a wild-type allele. The mutant allele does not encode a functional BADC protein. The increase in seed yield is at least 4%.

  • Publication number: 20220403403
    Abstract: A genetically modified plant that exhibits an increase in seed yield relative to a progenitor plant is disclosed. The genetically modified plant includes (a) a first homeolog of the SUGAR-DEPENDENT1 (SDP1) gene being homozygous for a wild-type allele; and (b) a second homeolog of the SDP1 gene being homozygous for a mutant allele. The wild-type allele encodes an active SDP1 triacylglycerol lipase and is identical to an allele of the first homeolog from the progenitor plant. The mutant allele does not encode an active SDP1 triacylglycerol lipase and includes one or more additions, deletions, or substitutions of one or more nucleotides relative to an allele of the second homeolog from the progenitor plant. The genetically modified plant expresses about 20% to 80% of SDP1 triacylglycerol lipase activity in seeds relative to the progenitor. The increase in seed yield is at least 10%.

  • Patent number: 10258965
    Abstract: The present invention relates to a method for preparing a sulfur-resistant catalyst for aromatics saturated hydrogenation, comprising the steps of: preparing noble metal impregnation solutions from a noble metal and deionized water or an acid solution; impregnating a carrier with the impregnation solutions sequentially from high to low concentrations by incipient impregnation; homogenizing, drying, and calcinating to obtain the sulfur-resistant catalyst for aromatics saturated hydrogenation. The catalyst for aromatics saturated hydrogenation prepared by the method according to the present invention is primarily used in processing low-sulfur and high-aromatics light distillate, middle distillate, atmospheric gas oil, and vacuum gas oil.
