Disclosures herein are directed to chemically defined animal-derived component free supplements designed for individual cell types that supports the ex vivo growth of cells as well or better than serum, in chemically defined conditions.

The disclosure discloses recombinant Bacillus subtilis for synthesizing guanosine diphosphate fucose and a construction method and application thereof. The recombinant Bacillus subtilis is obtained by intensively expressing guanylate kinase and nucleotide diphosphokinase genes and expressing exogenous fucokinase and phosphate guanylyltransferase genes in a genome of Bacillus subtilis 168. According to the disclosure, a bacterial strain for synthesizing the guanosine diphosphate fucose is obtained by reconstructing the Bacillus subtilis 168, with a volume of intracellular accumulation up to 196.15 g/L. According to the disclosure, by intensively expressing the guanylate kinase and nucleotide diphosphokinase genes, and enhancing the supply of intracellular GDP-L-fucose composition cofactors, the synthesis of the guanosine diphosphate fucose is promoted. The construction method for the recombinant Bacillus subtilis of the disclosure is simple and convenient to use, thus having good application prospects.

A method for producing an objective protein by using animal cells as an expression host is provided. The objective protein is produced by culturing animal cells having an objective protein-producing ability in the presence of an L-cysteine derivative such as (2RS,4R)-2-methyl-2,4-thiazolidinedicarboxylic acid 2-ethyl ester.

The present disclosure relates to methods of manufacture for producing anti-IL-12/IL-23p40 antibodies, e.g., the anti-IL-12/IL-23p40 antibody ustekinumab, and specific pharmaceutical compositions of the antibody.

The present invention relates to methods of modulating the mannose content of recombinant proteins.

The present invention relates to inorganic salts of nicotinic acid mononucleotides and compositions of Formula I, useful in the treatment of disorders and diseases associated with deficiencies in NAD.sup.+:

##STR00001##

wherein A, M.sup.1, M.sup.2, k, R.sup.1, R.sup.2, and R.sup.3 are as described herein.

Provided is a human-derived sensory neuron induction culture system. A combination of a small molecule inhibitor LY2157299 and a growth factor is added into a serum-free basal medium. Compared with an induction method involving serum, not only is the efficiency of inducing pluripotent stem cells into sensory neurons greatly improved, but the expression of a variety of ion channel proteins is also significantly improved, thereby achieving successful induction of multiple induced pluripotent stem cells from different sources into sensory neurons.

The present invention provides a system for providing a T cell product, including a T cell master cell bank and/or a T cell working cell bank.

A medium composition, containing a basic fibroblast growth factor (bFGF) at not less than 150 ng/mL is useful for culturing cells.

The present invention relates to processes to make neosaxitoxin, and analogues and variants thereof, and intermediates in the production of neosaxitoxin in recombinant host cells. Neosaxitoxin and the analogues and variants thereof may be used in the production of pharmaceutical compositions.
