摘要:
Disclosed are compositions and methods for identifying and preferably quantifying single antigens/molecules in tissue sections and other cell preparations. The methods make use of specific antibodies or aptomers linked with beads or other micro-particles using bright field microscopy having the purpose to identify and quantify single antigens or other molecules.
摘要:
The present invention relates to methods for evaluating tissue pre-treatment such as ischemic time, fixation time and alcohol time in an immunohistochemical assay by using one or more internal controls. Said internal controls may be biomarker specific or tissue specific. Also included are uses and kits comprising said internal controls.
摘要:
Disclosed is a method for measuring the effectiveness of therapy intended to kill malignant cells in vivo in a mammal, comprising the steps of obtaining monoclonal antibody that is specific to an internal cellular component of the mammal but not to external cellular components, wherein the monoclonal antibody is labeled; contacting the labeled antibody with tissue of a mammal that has received therapy to kill malignant cells in vivo, and determining the effectiveness of the therapy by measuring the binding of the labeled antibody to the internal cellular component. The internal cellular component is preferably insoluble intracellular antigen, and the label is preferably a radionuclide, a radiopaque material, or a magnetic resonance-enhancing material. Also disclosed is a method whereby the antibody to insoluble intracellular antigen is conjugated to an antineoplastic agent, so that upon administration of the antibody-antineoplastic agent conjugate, antineoplastic agent may be delivered to the tumor. Also disclosed are antibodies for use with the foregoing methods.

The invention relates to a new antigen termed BLA-36 specifically expressed on the surface of Hodgkin's cells, Reed-Sternberg cells and B lymphocytes, and to a new monoclonal antibody (anti-BLA-36) specific thereto. The antigen is characterized by the following properties:a molecular weight of about 36,000 D;the presence of an epitope recognized by antibody to said protein;specific expression by Hodgkin's cells and Reed-Sternberg cells in all subsets of Hodgkin's disease, and by activated and early proliferating B cells;no expression by T cells;capability of reacting with its antibody in both frozen and fixed/paraffin embedded tissues;a function associated with the growth of cells capable to express said antigen protein.

摘要:
Disclosed is a method for enhancing the effects of therapy that kills malignant cells in vivo comprising the steps of obtaining monoclonal antibody that is specific to an internal cellular component of a mammal but not to external cellular components, wherein the monoclonal antibody is attached to an antineoplastic agent; initiating therapy in a mammal to kill malignant cells in vivo, thereby causing some of the malignant cells to become necrotic; and administering the antibodies to the mammal. The antibodies bind to the necrotic malignant cells thereby delivering antineoplastic agent to surrounding cells. Also disclosed is a method of de novo therapy comprising administration of antibody-antineoplastic agent conjugate such that antineoplastic agent is delivered to the tumor. Also disclosed are antibodies for use with the foregoing methods and for use with diagnositc methods.

Methods for identifying Quantifiable Internal Reference Standards (QIRS) for immunohistochemistry (IHC). Also disclosed are methods for using QIRS to quantify test antigens in IHC.
摘要:
Disclosed are methods for identifying the presence of a tumor in a mammal, comprising the steps of obtaining an antibody against cell ghosts, wherein the antibody is specific to an intracellular antigen not present on the cell surface of normal or neoplastic cells, and wherein the antibody is labeled with a label capable of being imaged; administering the antibody to the mammal, thereby permitting the antibody to bind preferentially to necrotic tissue; and imaging the binding of the antibody to the necrotic tissue, wherein a localized concentration of said antibody is indicative of the presence of a tumor. The antibodies used in these methods are preferably monoclonal antibodies, are also preferably specific for one or more nuclear proteins, and are also preferably labeled with one or more radionuclides. Also disclosed are antibodies for use with the foregoing methods.
