Publication number: 20020004215Abstract: A method of labelling molecules which includes providing in a common medium a label molecule, a marker ligand able to bind a member of a specific binding pair, such as an antigen, a sbp member, an enzyme able to catalyze binding of the label molecule to other molecules, the enzyme being associated with the marker ligand; causing or allowing binding of the marker ligand to the sbp member; and causing or allowing binding of the label molecule to other molecules in the vicinity of the marker ligand bound to the sbp member. The marker ligand may be an antibody or any specific binding molecule, such as a chemokine or cytokine. A complementary member of the specific binding pair may be included, e.g. an antibody, or a diverse population of such sbp members, e.g. antibodies, may be included within which those which bind the counterpart sbp member, e.g. antigen, may be labelled and subsequently isolated for manipulation and/or use.Type: ApplicationFiled: January 23, 2001Publication date: January 10, 2002Applicant: Cambridge Antibody Technology, Ltd.Inventors: Jane Katharine Osbourn, Elaine Joy Derbyshire, John Gerald McCafferty, Tristan John Vaughan, Kevin Stuart Johnson

Patent number: 6291650Abstract: The invention provides methods and kits for producing specific binding pairs (sbp) members. Populations of polypeptide chain components of sbp members are combined to form libraries of sbps displayed by secreted replicable genetic display packages (rgdp). At least one of the polypeptide chains is expressed as a fusion with a component of an rgdp which thereby displays that polypeptide chain at the surface of rgdp. At least one population of polypeptide chains is expressed from nucleic acid which is capable of being packaged using a component of an rgdp, whereby the genetic material of rgdps produced encodes a polypeptide chain. The methods enable production of libraries of multimeric sbp members from a very large number of possible combinations. In one embodiment of the invention a method employs “chain shuffling” in the production of sbp members of desired specificity for a counterpart sbp member. Selection procedures are also described.Type: GrantFiled: June 25, 1998Date of Patent: September 18, 2001Assignees: Cambridge Antibody Technology, Ltd., Medical Research CouncilInventors: Gregory Paul Winter, Kevin Stuart Johnson, Andrew David Griffiths, Andrew John Hammond Smith

Patent number: 6225447Abstract: Methods, recombinant host cells and kits are disclosed for the production of members of specific binding pairs (sbp), e.g. antibodies, using display on the surface of secreted replicable genetic display packages (rgdps), e.g. filamentous phage. To produce a library of great diversity, recombination occurs between first and second vectors comprising nucleic acid encoding first and second polypeptide chains of sbp members respectively, thereby producing recombinant vectors each encoding both a fist and a second polypeptide chain component of an sbp member. The recombination may take place in vitro or intracellularly and may be site-specific, e.g. involving use of the loxP sequence and mutants thereof. Recombination may take place after prior screening or selecting for rgdps displaying sbp members which bind complementary sbp member of interest.Type: GrantFiled: June 17, 1998Date of Patent: May 1, 2001Assignees: Cambridge Antibody Technology Ltd., Medical Research CouncilInventors: Gregory Paul Winter, Kevin Stuart Johnson, Andrew David Griffiths, Andrew John Hammond Smith

Patent number: 5872215Abstract: Specific binding members for human carcinoembryonic antigen (CEA) comprise a human antibody antigen binding domain. The specific binding members may have a dissociation constant less than 1.0.times.10.sup.-8 M and may be substantially non-crossreactive with human liver and/or other normal tissues. They may be specific for the A3-B3 extracellular domain of CEA. They may be specific for a carbohydrate epitope of CEA. They may be produced by recombinant expression from encoding nucleic acid and modified and manipulated in various manners in accordance with known techniques. CEA is a tumour antigen and the specific binding members have proven ability to bind and target CEA both in vitro and in vivo.Type: GrantFiled: May 23, 1996Date of Patent: February 16, 1999Assignees: Medical Research Council, Cambridge Antibody Technology Ltd.Inventors: Jane Katharine Osbourne, Deborah Julie Allen, John Gerald McCafferty
