    摘要: A method is described for predicting the relative solubility of a polypeptide using polyethylene glycol (PEG) based volume exclusion precipitation. Different polypeptides can be tested for their solubilities relative to each other or relative to a reference. A single polypeptide can be tested for its relative solubility under different experimental conditions. The solubility determinations can be made by comparison based on graphs plotting the log solubility of the polypeptide against a range of PEG concentrations. Additionally, a method is provided for the high throughput visual or automated screening of multiple polypeptides for relative solubility differences, in a method that can omit the step of measuring the actual solubility or actual amount of precipitation of each sample at each PEG concentration.

    摘要: The present invention provides formulations for maintaining the stability of polypeptides, in particular, therapeutic antigen-binding polypeptides such as antibodies and the like, for example, anti-Aβ antibodies. The formulations generally include an antioxidant in a sufficient amount as to inhibit by-product formation, for example, the formation of high molecular weight polypeptide aggregates, low molecular weight polypeptide degradation fragments, and mixtures thereof. The formulations of the invention optionally comprise a tonicity agent, such as mannitol, and a buffering agent or amino acid such as histidine, and thus, the formulations are suitable for several different routes of administration.

    摘要: Formulations are described that are suitable for storage of proteins, such as antibodies, over a relatively broad range of protein concentrations, pH, and buffer types. Also described are methods of storing a protein and methods of identifying a suitable formulation for storage of a specific protein. In general, a formulation contains low to no surfactant, no to relatively low salt concentrations, and requires a relatively low buffer concentration.
