  • Publication number: 20230295666
    Abstract: Abstract: The present invention belongs to the field of biotechnology, and specifically relates to recombinant gene expression. The invention concerns a method of recombinant gene expression from a Chinese Hamster Ovary (CHO) cell, by using super-enhancer sequences for increased gene expression. Thus, the invention provides a method for producing an engineered CHO cell by introducing into the cell an exogenous nucleic acid molecule into or within 500 kb upstream or downstream of a super-enhancer as expression-enhancing sequence. The invention further provides an engineered CHO cell produced by the method. The invention further provides a method of producing a recombinant polypeptide. The invention is further directed to the use of a super-enhancer for transgene expression.

  • Publication number: 20170258726
    Abstract: The present invention relates to a process for spray-freeze-drying (SFD) a dispersion of polyelectrolyte complex (PEC) nanoparticles loaded with a protein drug, which yields a powdered product with adequate flowability properties that may readily be processed further into solid dosage forms such as tablets or capsules. The mean particle size of PEC nanoparticles obtained after redispersion of SFD powder or pharmaceutical compositions made from said powder in water is preserved in the nanometer range (<1000 nm), and so is the protein biological activity.
