  • Patent number: 9283273
    Abstract: A stable lyophilized protein formulation is described which can be reconstituted with a suitable diluent to generate a high protein concentration reconstituted formulation which is suitable for subcutaneous administration. For example, anti-IgE and anti-HER2 antibody formulations have been prepared by lyophilizing these antibodies in the presence of a lyoprotectant. The lyophilized mixture thus formed is reconstituted to a high protein concentration without apparent loss of stability of the protein.

  • Patent number: 5747002
    Abstract: Disclosed herein is a method for the preparation of sodium chloride formulations having a substantially uniform particle size suitable to ensure the dispersible properties for inhalation into the lungs of a subject. The formulations thus prepared are also the subject of this disclosure. The method involves jet milling coarse sodium chloride in one or preferably two or more procedures using air pressure suitable to produce particles having a significant fraction that are less than about 7 microns in size. Immediately following the milling, the particles are vacuum dried in an oven using a temperature and time suitable to cure the product to prevent substantial aggregation over time.

  • Patent number: 5192743
    Abstract: A formulation for proteins is provided that comprises a lyophilized mixture of a protein, a water-soluble etherified cellulose in an amount that upon reconstitution of the formulation will be sufficient to form a gel, and an excipient to facilitate rehydration of the gel and to maintain protein integrity during storage of the lyophilized gel product. When reconstituted to a gel, this formulation can be applied, for example, to tissue in need of treatment.

  • Patent number: 5055399
    Abstract: Enzyme-catalyzed synthetic reactions having otherwise unfavorable equilibria are facilitated by recovery of polypeptides by electrodialysis. A process of preparing polypeptides is provided that can be operated continuously to produce high yields of enriched polypeptides without recourse to post-synthetic product manipulations heretofore employed that are expensive and present a risk of residual toxic by-products. The invention is applied to advantage in the preparation of alpha-L-aspartyl-L-phenylalanine lower alkyl esters.
