The dispersion may be obtained by adding a stream of the aqueous hydrating agent solution to the organic polymer solution in a controlled fashion, or salt particles may be formed in the polymer solution by acid-base neutralization in solution. The coating solutions are storage stable. When applied to a medical device, the coating solution produces a homogeneous coating with desirable performance characteristics. The coatings of the invention adhere to the substrate but not to moist tissue with which they are placed in contact. The coatings of the invention provide indwelling devices with long-lasting lubricity after the device is inserted in a body.

Patent CA-2288600-A1 (CA)
Inventor: PRESTA LEONARD G
IPC: C07K16/00
Filed: 1998-04-30
Abstract: The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins and antibody-immunoadhesin chimeras. The invention also relates to the heteromultimers prepared using the method. Generally, the method provides a multispecific antibody having a common light chain associated with each heteromeric polypeptide having an antibody binding domain. Additionally the method further involves introducing into the multispecific antibody a specific and complementary interaction at the interface of a first polypeptide and the interface of a second polypeptide, so as to promote heteromultimer formation and hinder homomultimer formation; and/or a free thiol-containing residue at the interface of a first polypeptide and a corresponding free thiol-containing residue in the interface of a second polypeptide, such that a non-naturally occurring disulfide bond is formed between the first and second polypeptide. The method allows for the enhanced formation of the desired heteromultimer relative to undesired heteromultimers and homomultimers.

Title: Processes for producing citrate esters
Inventor: CHIU KUEN-WAI
IPC: C07C67/08
Filed: 1998-05-12
Abstract: Described are processes for producing citrate esters in an economic fashion.  Esters are prepared by esterification of a citric acid-containing fermentation broth having been treated to remove cations and optionally other impurities, but containing sugar(s). Esters are also prepared by reacting an impure aqueous citric acid source with an alcohol to provide a heterogeneous acqueous/organic reacted mixture, wherein the organic phase contains the ester and the acqueous phase retains water-soluble impurities. A liquid phase separation is then used to separate the organic and aqueous phases, conveniently separating the impurities from the product and avoiding the energy-intensive distillation of water from the reaction medium.
