The present invention pertains to methods for manufacturing high titer antibody products. In particular, the invention pertains, in part, to improved serum-free animal cell culture medium, which can used for the production of a protein of interest. Additionally, the present invention further pertains to chromatographic procedures employed to successfully isolate the antibody product subject of the present disclosure.

A method for controlling microbial growth in an ethanol fermentation system is disclosed wherein the method comprises: (a) adding a biocide including a peroxy acid (e.g., peracetic acid) into a fermentable medium, wherein the biocide is essentially free of chelating agents; and (b) fermenting the fermentable medium with yeast to produce a fermented medium including ethanol. The method may further comprise: (c) distilling the fermented medium to separate at least a portion of the ethanol from solids in the fermented medium; and (d) producing a distillers grain product from the solids. By using a biocide essentially free of chelating agents, the method does not introduce undesirable chelating compounds into the co-product non-fermentable solids of ethanol production that are processed into distillers grain products.

The present disclosure relates to methods and compositions for reprogramming cells to a pluripotent state. In particular, it relates to an integration- and feeder cell-free method for reprogramming primary human fibroblast cells to induced pluripotent stem cells (iPSCs).

Increasing therapeutic activity of fibroblasts through suppression of complement activation is disclosed. Embodiments of the disclosure teach that viability of fibroblasts in blood and/or in vivo is increased by inhibition of complement activation. In another embodiment, the blockade of complement is utilized to enhance ability of fibroblasts to suppress inflammation, stimulate generation of T regulatory cell, and inhibit pathologic T cell responses. Other enhancements of fibroblast activity disclosed as a results of complement activation include stimulation of cytokine production, release of antimicrobial and/or antiviral proteins, as well as enhancement of regenerative activities.

Delivering a payload across a plasma membrane of a cell includes providing a population of cells and contacting the population of cells with a volume of an aqueous solution. The aqueous solution includes the payload and alcohol content greater than 5 percent concentration. The volume of the aqueous solution may be a function of exposed surface area of the population of cells, or may be a function of a number of cells in the population of cells. Related compositions, apparatus, systems, techniques, and articles are also described.

The present invention pertains to methods of producing polypeptide of interest in cell cultures lacking glutamine. The present invention further pertains to a method of producing a protein of interest in a large scale cell culture, comprising supplementing the cell culture with nucleic acid synthesis precursors and/or corticosteroids.

A buffer for the capacitation of spermatozoa consisting of a buffer solution comprising the active ingredient Astaxanthin, in combination with serum albumin and a phosphate buffer solution made up of monobasic potassium phosphate KH.sub.2PO.sub.4 buffered with dibasic potassium phosphate K.sub.2HPO.sub.4.

A system and method for generating an incubated bacteria solution by heating a nutrient germinant composition and bacteria, including at least one species in spore form, to a preferred temperature a range of 35-50° C. for 2-60 minutes using exothermic chemical reaction heat. An incubated bacteria solution is preferably generated at or near a point-of-use in an aquaculture, agriculture, wastewater, or environmental remediation application. The nutrient-germinant composition comprises L-amino acids, optionally D-glucose and/or D-fructose, a buffer, an industrial preservative, and may include bacteria spores (preferably of one or more Bacillus species) or they may be separately combined for incubation. A first chemical contained in a pouch is activated by contact with a second chemical, water, or air in a flameless heater to initiate exothermic reaction to provide incubation heat. A potable, single-use incubation bag is configured to hold the flameless heater and a container of nutrient germinant composition and spores.
