Currently, mammalian cell line development technologies used by most biopharmaceutical companies are based on either the methotrexate (MTX) amplification technology or the glutamine synthetase (GS) system. With both systems, the cell clones obtained are highly heterogeneous, as a result of random genome...

mammalian cell systems are not normally used for routine production of recombinant proteins because (1) they usually require a huge effort to generate a stable cell line, which is expensive to grow in large quantities (2) the expression levels are sometimes low, and (3) mammalian cells grow ...

The 293T-CHYRON20 cell line was transfected with Cas9 and TdT to induce insertions, then single colonies isolated. The clonal isolate shown bears the insertions CTGAAAAACT and CCT. This cell line was treated and sequences analyzed as in Fig. 3d. Editing outcomes were determined to be the ...
DNA methylation is of paramount importance for mammalian embryonic development. DNA methylation has numerous functions: it is implicated in the repression of transposons and genes, but is also associated with actively transcribed gene bodies and, in some
The recombinant cell line, the culture media and the process settings affect these quality attributes [4, 5]. During process development, it is important to ensure a reproducible, distinct and preferably homogenous pattern of the product. For the establishment of biosimilars, it is important to ...
The purpose of this study is to establish a new mammalian cell line stably and efficiently expressing virus-like particle of JEV for potential use of JEV subunit vaccine. Results We generated a new cell clone (BJ-ME cells) that stably produces a secreted form of Japanese encephalitis virus (...
2b). A second capped peptide, CAP-GDNF (pGlu-AAAASPENSRGK-NH2), mapped to amino acids 94-106 of GDNF (glial cell line-derived neurotrophic factor) (Fig. 2b). Classically, FGF5 is a so-called “paracrine” member of the fibroblast growth factor (FGF) family and has diverse roles, ...
Alternatively, if cells grow linearly, a timer results in cells growing by the same amount each cell cycle, therefore maintaining size homeostasis12. In bacteria and yeast, the development of high-throughput single live cell imaging has provided a wealth of measurement which, together with the ...
