  • Patent number: 9330413
    Abstract: Methods and apparatus are disclosed provide various enhancements and/or improvements to the conventional shopping process used by brick-and-mortar stores. In some embodiments, a customer may use a mobile computing device, such as a smart phone, to select and pay for items in a brick-and-mortar store. Such shopping process may permit the customer to purchase numerous items without the using of shopping basket or a wheeled shopping cart. The shopping process may further permit the customer to pay for items and leave the store with such items without waiting in a checkout line.

  • Publication number: 20160115225
    Abstract: Methods are provided for controlling the levels of acidic species when a protein of interest is expressed by host cells. One particular example of an acidic species is methylglyoxal (MGO). Reduction of acidic species such as MGO may be achieved by regulating the glucose consumption of the cell culture or by modulating the cysteine/glutathione metabolic pathways.
