An object is to provide a leucine-rich α2 glycoprotein composition comprising leucine-rich α2 glycoprotein and having excellent preservation stability. The object can be achieved by a leucine-rich α2 glycoprotein composition comprising leucine-rich α2 glycoprotein and having a pH of 7.0 to 9.3.

Leucine-rich ALPHA2 glycoprotein composition

An object of the present invention is to provide a measurement method and a reagent for measurement which can measure LRG in a biological sample simply in a short time. The present inventors have intensively studied to achieve the object and made findings that LRG in a biological sample can be measured simply in a short time by an immunoagglutination measurement method in which the biological sample is brought into contact with insoluble carrier particles carrying a first anti-LRG monoclonal antibody and insoluble carrier particles carrying a second anti-LRG monoclonal antibody in a liquid phase, and the invention has been thus completed.

Immunoassay and measurement reagent for leucine-rich alpha2 glycoprotein

The purpose of the present invention is to produce a chimeric antigen receptor (CAR) specific to glypican-1 (GPC-1) and to treat squamous cell carcinoma with genetically modified cells capable of expressing the CAR. The present invention provides: a chimeric antigen receptor for use in the treatment and/or prevention of squamous cell carcinoma, said chimeric antigen receptor comprising an extracellular domain capable of binding to GPC-1, a transmembrane domain and one or multiple intracellular domains, wherein at least one of the intracellular domains is an intracellular domain containing a primary cytosolic signaling sequence or an intracellular domain containing both a primary cytosolic signaling sequence and a secondary cytosolic signaling sequence; a genetically modified cell capable of expressing the chimeric antigen receptor; and a cell preparation containing the cell.

Anti-glypican-1-immunizing antigen receptor

According to the present disclosure there are provided compositions and methods for treating malignant tumors, including an anti-LSR (lipolysis stimulated lipoprotein receptor) antibody that comprises the presently disclosed antibody heavy and light chain complementarity determining region (CDR) sequences, or an antigen-binding fragment thereof, or a functional equivalent thereof. Further provided for treating an LSR-positive malignancy is an LSR antagonist or an LSR inhibitor such as a nucleic acid. Therapeutic administration of the anti-LSR antibody to a subject having an LSR-positive malignant tumor is also described.

Therapeutic drug for malignant tumors

The present invention relates to an esophageal cancer marker and application thereof. The present invention relates to: a marker that includes Glypican-1 or an expression product thereof, or a fragment or derivative thereof, and serves to identify esophageal cancer; a detection agent that includes a substance that binds to Glypican-1 or an expression product thereof; and a composition that includes a Glypican-1 inhibitor and serves to prevent or treat esophageal cancer. Herein, Glypican-1 can be SEQ ID NO: 1 (nucleic acid sequence) or SEQ ID NO: 2 (amino acid sequence), or an equivalent thereof.

Esophageal cancer marker and use thereof

Provided are a novel prophylactic and/or therapeutic drug for an inflammatory disease and a method for searching for the same. A prophylactic and/or therapeutic agent for an inflammatory disease that comprises a substance capable of inhibiting the expression or function of leucine rich alpha 2 glycoprotein (LRG). A method of screening for an anti-inflammatory substance using LRG or an LRG-expressing cell, wherein the inhibition of the expression or function of LRG is used as an index.
