Hybridoma cell line that secrets cyproheptadine monoclonal antibodies and preparation method thereof
A hybridoma cell line of secreting cyproheptadine monoclonal antibodies with a preservation number of CGMCC No. 14699 belongs to the field of food safety immunological detection. BALB/c mice are immunized through one time immunization with complete freund's adjuvant, three times of booster immunization with incomplete freund's adjuvant and one time of rush immunization with cyproheptadine complete antigen without adjuvant; the spleen cells from BALB/C mice immunized with high potency and low value of IC50 are fused with murine myeloma cells; and then the hybridoma cell line is obtained through indirect competitive ELISA screening and three sub-clones. The monoclonal antibody secreted by this cell line has good specificity and detection sensitivity to cyproheptadine (value of IC50 is 0.37 ng/ml), being suitable for detection of cyproheptadine in food.

MATRIX BOUND VESICLES (MBV) FOR TREATMENT OF ACUTE RESPIRATORY DISTRESS SYNDROME
Methods are disclosed for treating an acute respiratory distress syndrome, such as an acute respiratory distress syndrome associated with a viral infection, such as SARS-CoV2 (COVID-19) in a subject in need thereof. These methods include administering to the subject a pharmaceutical preparation comprising isolated matrix bound vesicles (MBV) derived from extracellular matrix.
ANTIBODY FOR DETECTING ACETYLATION OF COX2 PROTEIN, AND USES THEREOF
The present invention relates to an antibody for detecting acetylation of COX2 protein, and uses thereof, and more specifically, to an antibody that specifically recognizes the acetylation of S565 residue of the COX2 protein; and uses thereof for diagnosing neurodegenerative diseases or inflammatory diseases. An antibody or a functional fragment thereof according to the present invention specifically binds to an acetylated residue of COX2 protein, and can thus be very effectively used for diagnosing neurodegenerative diseases, inflammatory diseases, and the like in which the degree of acetylation of S565 residue of the COX2 protein is reduced.

Antibodies that bind tumor tissue for diagnosis and therapy
Provided herein are antibodies that bind to tumor tissue through a binding interaction with an extracellular RNA-protein complex. Such antibodies are used in methods of inducing an immune response and methods of inhibiting tumor cell growth. Additionally provided are methods of producing such antibodies.
High-speed in vitro screening method
The purpose of the present invention is to provide a method for identifying antibody CDR3 clusters using high speed in vitro screening a library selected from the group consisting of cDNA library and nucleic acid aptamer library comprising: (i) preparing a positive spherical shaped structure by binding a target molecule to a spherical shaped molecule, wherein the target molecule is immobilized on the positive spherical shaped structure, wherein the positive spherical shaped structure may contain a fluorescent label; (ii) preparing a negative spherical shaped structure, wherein the target molecule is not immobilized on the negative spherical shaped structure, wherein the negative spherical shaped structure may contain a fluorescent label; (iii) forming a positive spherical shaped conjugate or a negative spherical shaped conjugate by binding a target detecting molecule capable of binding to the target molecule to the positive spherical shaped structure or to the negative spherical structure, wherein the target detecting molecule is selected from the library having a size equal to or more than 10.sup.10 or equal to or less than 10.sup.14, wherein the target detecting molecule may contain a fluorescent label; (iv) separating the positive and the negative spherical shaped conjugates using a fluorescence cell sorter; (v) selecting the separated positive and the separated negative spherical shaped conjugates at least 1 time and then eluting the selected conjugates to obtain an eluted sample; (vi) amplifying a nucleic acid in the eluted sample using PCR to obtain PCR products; (vii) separating the PCR products using the fluorescence cell sorter; and (viii) conducting amplicon sequencing for CDR3 cluster analysis to identify the antibody CDR3 clusters.
HOMODIMERIC PROTEIN CONSTRUCTS
The present invention relates to novel recombinant fusion proteins, such as human antibody-based molecules called Vaccibodies, which are able to trigger both a T cell- and B cell immune response.
