摘要： Described herein are compositions and methods for identifying, selecting, or culturing cells comprising a subject nucleic acid sequence of interest. Generally, a nucleic acid comprising a subject nucleic acid and a sequence encoding an enzyme molecule involved in biosynthesis of an amino acid is introduced into a cell. The cell is then grown on media lacking the amino acid, such that cells comprising the introduced nucleic acid are capable of growth. In some instances, the cell further comprises an inhibitor of the enzyme molecule to increase the stringency of the selection.

摘要： A method for delivering a processing solution includes providing a concentrated processing solution in a bioprocess container, the concentrated processing solution being produced at a first site. The method also includes combining the concentrated processing solution with a biopolymer containing solution produced in a bioreactor at a second site different from the first site. In some embodiments, the processing solution is a buffer for processing products of cells cultured in a bioreactor. A system and a pharmaceutical production facility for carrying out the method is also provided.

摘要： A recombinant eukaryotic host cell expressing a gene of interest (GOI) which is engineered by genetic modifications to increase expression of two or more genes encoding translation initiation factors (TIF genes) of the messenger ribonucleoprotein (mRNP), compared to the host cell prior to said one or more genetic modifications, wherein said TIF genes comprise at least a gene encoding eIF4A and a gene encoding eIF4G, and wherein expression of at least one of said TIF genes is under transcriptional control of a promoter different from the promoter controlling expression of said GOI.

摘要： A method of reducing precipitation in a bacterial fermentation process for producing a fermentation product, which fermentation process comprises the steps:
a) cultivating the host cells for bacterial growth in a batch phase using a batch medium; and
b) cultivating the host cells for producing the fermentation product in a fed-batch phase using a feed medium;
which feed and batch media are each unprecipitated media solutions, wherein:
i) the batch medium comprises an amount of calcium salts, magnesium salts, phosphate salts and at least one chelating agent, which is a citrate salt and/or citric acid at an amount of at least 5 mM, and/or EDTA at an amount of at least 1 mM; and
ii) the feed medium comprises an amount of calcium salts which is at least 1 mM, and which is at least 5-fold higher as compared to the batch medium (M/M); and
iii) the feed medium comprises an amount of magnesium salts which is at least 3 mM, and which is at least 2-fold higher as compared to the batch medium (M/M); and
iv) the feed medium comprises an amount of phosphate salts which is less than 90% of the amount comprised in the batch medium (M/M).-

摘要： A bioprocess system and a method for incubating, growing and harvesting cell cultures is described. Also disclosed is a bioprocess container that can be used with the system. In one aspect of the present disclosure, the bioprocess system includes bioprocess tubes and cell culture tubes having particular dimensions and being made from specific materials that allow the tubes to be welded together while preventing open connections and/or ruptures. In this manner, bioprocess containers can be connected and disconnected from a cell culture apparatus without having to perform the manipulation within a closed environment and without associated monitoring.
