Patent number: 6677433Abstract: Disulfide proteins showed mitigated allergenicity and increased digestibility by pepsin following reduction by thioredoxin. The sulfhydryl groups newly formed on reduction by thioredoxin (at 4° C.) or dithiothreitol (DTT) (at 55° C.) were blocked with a physiological disulfide, such as cystamine or oxidized glutathione (GSSG) to obtain stable forms of the disarmed allergen. When derivatized with cystamine, BLG was separated from its oxidized and reduced forms on non-reducing SDS-PAGE and appeared to lack sulfhydryl groups. Although less effective GSSG, gave similar results. Allergenicity of the two derivatives was compared with that of the oxidized, reduced and reoxidized forms of BLG by skin testing dogs from a colony sensitized to cow's milk. Both the cystamine and GSSG derivatized BLG showed decreased allergenicity and increased sensitivity to pepsin as compared to controls. The reoxidized form resembled the derivatives in having lower allergenicity.Type: GrantFiled: February 7, 2001Date of Patent: January 13, 2004Assignee: The Regents of the University of CaliforniaInventors: Bob B.

Patent number: 6262019Abstract: Glutathione (GSH) is a tripeptide of extreme importance as a catalyst, reductan, and reactant. It can be depleted intracellulary either by forming a direct complex with an electrophilic agent (accomplished investigationally by agents such as bromobenzene or diethyl maleate), by way of inhibition of synthesis, or by subjecting cells to oxidant stress. Most cells, except for epithelia cells, do not have a direct transport capacity for intact GSH. Non-epithelial cells must either transport precursor substrates for GSH synthesis or salvage amino acids from circulating GSH for reuse in intracellular resynthesis. Dietary cysteine is a rate limiting substrate for the synthesis of glutathione and also inhibits GSH efflux. Although GSH is synthesized from precursors in virtually all cells, the liver is the main source of plasma GSH. Protection and support of liver function is paramount to elevating GSH levels.Type: GrantFiled: April 29, 1999Date of Patent: July 17, 2001Assignee: Vit-Immune, L. C.Inventors: Robert H Keller, David W Kirshenbaum

Patent number: 5679780Abstract: High quality protein products are obtained from whey by subjecting whey to cross flow filtration in microfilter. The whey and retentate are brought to circulate in a circulation path on one side of the membrane area of the microfilter, while whey which has passed through the membrane area (permeate) is circulating in a second path on the other side of the membrane area in such a way that the pressure drop through the whole membrane area is kept constant and below 0.8 bar. With this technique, there is obtained a fractionation of milk serum protein such that denatured milk serum protein and fat are retained in the retentate and undenatured milk serum protein passes through the membrane into the permeate. With a subsequent treatment there is obtained a whey protein product which is rich is .alpha.-lactalbumin and .beta.-lactoglobulin and has a low fat content.Type: GrantFiled: January 3, 1995Date of Patent: October 21, 1997Assignee: Tetra Laval Holdings & Finance S.A.Inventors: John Jensen, Peter Henrik Larsen

Process for the recovery of .alpha.-lactalbumin and .beta.-lactoglobulin from a whey protein product
Patent number: 5420249Abstract: This invention relates to a process for the recovery of .alpha.-lactalbumin and/or .beta.-lactoglobulin enriched whey protein concentrate from a whey protein product. The process comprises the following steps:a) incubating a solution comprising whey protein product with a calcium-binding ionic exchange resin in its acid form to initiate the instabilization of .alpha.-lactalbumin,b) adjusting the pH of the treated protein product solution to a value between 4.3 and 4.8, after separation of the resin,c) incubating the protein product solution at a temperature between 10 and 50.degree. C. to promote the flocculation of .alpha.-lactalbumin,d) fractionating the proteins in the protein product solution at pH 4.3-4.8, providing an .alpha.-lactalbumin enriched fraction and a .beta.-lactoglobulin enriched fraction,e) raising the pH of the .alpha.-lactalbumin enriched fraction sufficiently to solubilize the .alpha.-lactalbumin fraction, andf) optionally raising the pH of the .beta.Type: GrantFiled: December 20, 1993Date of Patent: May 30, 1995Assignee: Campina Melkunie B.V.Inventors: Jacobus N. de Wit, Henricus Bronts -

Patent number: 5290571Abstract: The present invention is concerned with a whey protein composition comprising a suitable concentration of whey protein concentrate wherein the whey protein concentrate contains proteins which are present in an essentially undenatured state and wherein the biological activity of the whey protein concentrate is dependent on the overall amino acid and small peptides pattern resulting from the contribution of all its protein components and a method of producing said whey protein composition. The invention also relates to several applications of said composition.Type: GrantFiled: October 4, 1989Date of Patent: March 1, 1994Assignee: Immunotec Research Corporation, Ltd.Inventors: Gustavo Bounous, Phil Gold, Patricia A.

Patent number: RE39705Abstract: Glutathione (GSH) is a tripeptide of extreme importance as a catalyst, reductan, and reactant. It can be depleted intra-cellularly either by forming a direct complex with an electrophilic agent (accomplished investigationally by agents such as bromobenzene or diethyl maleate), by way of inhibition of synthesis, or by subjecting cells to oxidant stress. Most cells, except for epithelia cells, do not have a direct transport capacity for intact GSH. Non-epithelial cells must either transport precursor substrates for GSH synthesis or salvage amino acids from circulating GSH for reuse in intracellular resynthesis. Dietary cysteine is a rate limiting substrate for the synthesis of glutathione and also inhibits GSH efflux. Although GSH is synthesized from precursors in virtually all cells, the liver is the main source of plasma GSH. Protection and support of liver function is paramount to elevating GSH levels.Type: GrantFiled: November 26, 2001Date of Patent: June 26, 2007Assignee: Vit-Immune, L.C.Inventors: Robert H. Keller, David Kirchenbaum
