Abstract: The present invention pertains to methods of preventing and eliminating trisulfide bonds in proteins such as antibodies. In one embodiment, trisulfide bonds in proteins are converted to disulfide bonds as part of chromatographic purification procedures. In another embodiment, the formation of trisulfide bonds in proteins is inhibited by implementation of methods described herein during the cell culture production of such proteins. In another embodiment, monoclonal antibodies are produced by the methods described herein.

Abstract: The present invention is related to methods for preventing or retarding (i.e., inhibiting) yellow color or peroxide formation in a composition. The present invention is also related to methods of reducing or decreasing the amount of yellow color or peroxide in a composition. More specifically, the present invention relates to the use of an antioxidant, an oxygen scavenger, pH, a chelating agent, and/or at least two factors in the methods of the invention. The present invention is also related to methods for predicting the rate of yellow color or peroxide formation in a composition.

Abstract: Specific, highly potent 2-oxo-amide based inhibitors of phospholipase A2 (PLA2) activity are provided. A role for PLA2 activity in spinally mediated inflammatory processes is established, and a method for treating hyperalgesia and other inflammatory conditions associated with PLA2 activity is provided.
