Publication number: 20150071944Abstract: The invention provides compositions and methods for inhibiting fractionation of immunoglobulins comprising a lambda light chain based on the observation that iron, in the presence of histidine, results in increased fragmentation of a recombinant fully human IgG molecule containing a lambda light chain due to cleavage in the hinge region. The invention further provides an aqueous pharmaceutical formulation comprising an antibody, or antigen-binding portion thereof, that binds the p40 subunit of IL-12/IL-23 and a buffer system comprising histidine, wherein the formulation has enhanced stability, including enhanced resistance to fragmentation.Type: ApplicationFiled: November 6, 2014Publication date: March 12, 2015Inventors: Ivan R.S.

Patent number: 8871201Abstract: 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.Type: GrantFiled: August 12, 2005Date of Patent: October 28, 2014Assignee: Wyeth LLCInventors: Li Li, Angela Kantor, Shannon B.

Patent number: 8865174Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human interleukin-12 (hIL-12) are disclosed. Preferred antibodies have high affinity for hIL-12 and neutralize hIL-12 activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hIL-12 and for inhibiting hIL-12 activity, e.g., in a human subject suffering from a disorder in which hIL-12 activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.Type: GrantFiled: March 12, 2012Date of Patent: October 21, 2014Assignee: AbbVie Inc.Inventors: Jochen G.

Publication number: 20080003686Abstract: 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.Type: ApplicationFiled: May 17, 2007Publication date: January 3, 2008Applicant: WyethInventors: Li Li, Angela Kantor, Nicholas Warne
