6612 results about "Lactose" patented technology

Lactose is a disaccharide. It is a sugar composed of galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose makes up around 2–8% of milk (by weight). The name comes from lac (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars. The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste. It is used in the food industry.

Product quality enhancement in mammalian cell culture processes for protein production

The present invention describes methods and processes for the production of proteins, particularly glycoproteins, by animal cell or mammalian cell culture, illustratively, but not limited to, fed-batch cell cultures. The methods comprise feeding the cells with D-galactose, preferably with feed medium containing D-galactose, preferably daily, to sustain a sialylation effective level of D-galactose in the culture for its duration, thus increasing sialylation of the produced proteins. The methods can also comprise at least two temperature shifts performed during the culturing period, in which the temperature is lower at the end of the culturing period than at the time of initial cell culture. The cell culture processes of the invention involving two or more temperature shifts sustain a high cell viability, and can allow for an extended protein production phase. The methods can also comprise the delayed addition of polyanionic compound at a time after innoculation. Supplementation of the cultures with D-galactose, preferably in a feed medium, to sustain galactose at sialylation effective levels in the cultures until the end of a culture run reverses a decline in sialylation that accompanies culture scale up, and is advantageous for large scale culturing processes.

Formulation of powder containing nanoparticles for aerosol delivery to the lungs

Respirable particles carrying active principles or diagnostics in nanoparticle form are created by mixing the nanoparticles with liquid carrier, then forming the resultant mixture into respirable particles. Spray-drying, freeze spray drying and drying followed by comminution may be used to create the respirable particles, which may be delivered to the lung via a dry powder inhaler. In one example, lactose was used as the excipient and spray-dried with two different types of nanoparticle: gelatin and poly butylcyanoacrylate nanoparticles. The incorporation of nanoparticles did not affect the respirable fraction of the carrier powders.
