The present disclosure relates to reversal agents, which specifically bind to anti-Factor XI and/or anti-Factor XIa antibodies, and reverse one or more anticoagulant effects of the anti-Factor XI and/or anti-Factor XIa antibodies, as well as to methods of use thereof, such as methods for reversing anticoagulant effects of such anti-Factor XI and/or anti-Factor XIa antibodies, and to related methods for managing bleeding or bleeding risks.
摘要:
The present invention is concerned with antigen binding polypeptides, and in particular conventional antibodies derived from camelid species, that specifically bind to target antigens that are either self-antigens or highly conserved antigens. The present invention also relates to anti-idiotype antigen binding peptides which bind to a target antigen comprising the variable region of an antibody obtained from a species within the family Camelidae.
摘要:
Provided are monoclonal antibodies that detect CD19 CAR-modified immune cells and CAR-modified immune cells irrespective of the tumor associated antigen they target. Methods of using these functional monoclonal antibodies include, but are not limited to, detection, quantification, activation, and selective propagation of CAR-modified immune cells.
摘要:
Polypeptides which have binding activity to an Fc region of immunoglobulin G and can be favorably used in detecting, purifying, immobilizing or removing an antibody, immunoglobulin G or a protein containing an Fc region of immunoglobulin G, are described. Methods for detecting, purifying, immobilizing or removing an antibody, immunoglobulin G or a protein containing an Fc region of immunoglobulin G, by using the peptide, are also described.

In certain embodiments, the present invention provides a method of treating an Interferon gamma inducible protein 10 (IP-10)-related disease in a subject, comprising: (a) administering to the subject a predetermined dosage of an anti-IP-10 antibody; (b) detecting the level of the anti-IP-10 antibody in a sample of the subject; and (c) if the level of the anti-IP-10 antibody from step (b) is below a threshold exposure level, increasing the dosage of the anti-IP-10 antibody in the subject such that the IP-10 related disease in the subject is treated. In certain embodiments, the present invention provides an isolated monoclonal anti-idiotypic antibody, or an antigen binding portion thereof, which binds to the anti-IP-10 antibody MDX-1100.
摘要:
The present invention is related to the obtaining of modified antibodies by means of DNA recombinant technology from the murine monoclonal antibody P3 (MAb P3), produced by the hybridoma cell line deposited under Budapest Treaty with accession number ECACC 94113026, and from its anti-idiotype murine monoclonal antibody 1E10(MAbai 1E10), produced by the hybridoma cell line with deposit number ECACC 97112901, with the objective of achieving monoclonal antibodies which preserve the biological function of specifically binding the antigen of the original antibodies, but being at the same time less immunogenic. The chimeric antibodies of the invention contain the variable domains of the murine immunoglobulin and the constant regions of the human immunoglobulin; and those humanized, besides containing the constant regions of the human immunoglobulins, are modified in the murine framework regions (FRs), in particular, in those zones that could be in a T cell antigenic site, so that several positions of the FRS are human as well. These antibodies can be used in the diagnosis and therapy of different types of tumors. The present invention is also related to the use of the antibodies for therapeutic and diagnostic purposes.
摘要:
Peptides generated from a random library that are bound by a monoclonal antibody to Chlamydial glycolipid exoantigen (GLXA) and thus mimic this antigen are disclosed. Peptides that correspond to antigen-binding regions of an anti-idiotypic antibody (mAb2) specific for anti-GLXA antibody (Ab1) which act as molecular mimics of GLXA are also disclosed used as immunogens to induce broadly reactive genus-specific anti-chlamydial antibodies. These peptides and immunogenic DNA encoding the mAb2-like peptides, microparticle or nanoparticle formulations and other formulations of these peptides are disclosed as are methods for immunizing subjects to obtain genus-specific anti-chlamydial antibodies and to treat or prevent Chlamydia-associated or induced rheumatoid arthritis.
摘要:
Polypeptide linkers with defined tertiary structures, usually of defined alpha helical structure, are used to join two domains in a fusion protein. In one embodiment of the invention, a method is provided for the cell-free synthesis of the fusion protein.
摘要:
An immunoassay device capable of assaying amount of an antigen by allowing a labeled antibody to specifically bind to a antigen analyte in a sample and assaying a label of a bound product, an interior of a single device has four regions comprises: (1) a first region where the antigen in the sample reacts with a first antibody that is the labeled antibody capable of specifically binding to the antigen, (2) a second region where first antibody that has not bound to the antigen reacts with a second biotin- or avidin-bound antibody, (3) a third region where, depending on whether the second antibody is biotin-bound antibody or avidin-bound antibody, either avidin or biotin is immobilized by immobilization means so as to be unable to move to the fourth region, and the second antibody is captured by the immobilized avidin or biotin, and (4) a fourth region where the label of the first antibody that has bound to the antigen is detected, being constructed in such a way that a solution can move sequentially through each region, the first antibody, which is the labeled antibody such that an antibody component is an F(ab′) fragment or reduced IgG, the F(ab′) fragment or reduced IgG being bound with the label in a predetermined proportion, is included in the first region or an adjacent region, and the second antibody is a biotin- or avidin-bound antibody, being of anti-idiotype antibody against the first antibody and a type that cannot bind to the bound product of the antigen and first antibody, and is included in the second region or an adjacent region.
