US Patent:

6525176, Feb 25, 2003

Filed:

Jul 7, 2000

Appl. No.:

09/612592

Inventors:

Vivian W. Lee - Alamo CA
Kris P. Antonsen - Berkeley CA

Assignee:

PPL (Holdings) Limited - London

International Classification:

C07K 100

US Classification:

530350, 530413, 530416, 530380, 530392, 530395, 530830

Abstract:

A method for purifying human or other alpha-l proteinase inhibitor ( -PI) from a solution (which may be derived from the milk of a transgenic animal expressing the -PI) which comprises contacting the solution with a cation exchange substrate under conditions sufficient to bind non-tg- -PI contaminants to the substrate while not substantially binding tg -PI to the substrate. Using the preferred embodiment, the purified tg -PI contains as little as 40 pg non- -PI-whey protein per mg total protein.

US Classification:

530413

Abstract:

A method for purifying human or other alpha-1 proteinase inhibitor (. alpha. sub. 1 -PI) from a solution (which may be derived from the milk of a transgenic animal expressing the. alpha. sub. 1 -PI) which comprises contacting the solution with a cation exchange substrate under conditions sufficient to bind non-tg-. alpha. sub. 1 -PI contaminants to the substrate while not substantially binding tg. alpha. sub. 1 -PI to the substrate. Using the preferred embodiment, the purified tg. alpha. sub. 1 -PI contains as little as 40 pg non-. alpha. sub. 1 -PI-whey protein per mg total protein.

US Classification:

435 724

Abstract:

A method of controlling the amount of a biologically active substance binding to a cell surface having both receptors to the substance and receptors for the Fc domain of an antibody that can complex with the substance or other antibodies that can complex with the substance. By exploiting the generally more numerous Fc receptor sites, substance binding can be increased and/or controlled. Method contemplates controlling amounts of substances such as cytokines, hormones, and growth factors that are associated with cells such as monocytes, macrophages, granulocytes, B cells, T cells, and platelets. Method is illustrated using conjugated antibodies to tissue necrosis factor (TNF) to increase the binding of TNF to monocytes.

Assignee:

Miles Inc. - Elkhart IN

International Classification:

C07K 312
C07K 322

US Classification:

53038823

Abstract:

Method of purifying a protein from a solution of substances comprising the steps of passing the solution through an ion exchange material at a pH which facilitates binding of the protein of interest, washing the bound protein at a different pH at which the bound protein does not elute but which the free protein would not bind to the ion exchange material, and then eluting the protein at a pH which facilitates elution. Method is especially useful in purification of antibodies such as antibodies to tumor necrosis factor.

International Classification:

A61M 37/00

US Classification:

604 46

Abstract:

A low-profile applicator, and a method of manufacturing and use thereof, for impacting microneedles against the stratum corneum of a person having a housing, a diaphragm member having the microneedles, a folding member having interlinking members that hinge-ably rotate with a force member, operatively attached thereto, between a resting position and an extended position. The folding member translates energy stored within the force member when release while retaining the force member in an energized state when in the resting position.
