ANTI-GALACTOFURANOSE ANTIBODIES FOR DETECTING AND TREATING ASPERGILLOSIS

It is provided novel anti-galactofuranose antibodies and their use for diagnosis of and/or treating aspergillosis, and for the design of chimeric antigen receptor T-cells, wherein single chain variable fragment of the antibodies, such as a heavy chain variable region or a light chain variable region, is fused via a spacer and a transmembrane domain to a signaling endodomain to generate an expression cassette that will be integrated into a T cell.

Extraction of mycotoxins

A method and composition for extracting an analyte from a test sample such as grain, so as to determine whether the test sample is contaminated with a toxin. The method is particularly useful for detecting the presence in a batch of grain of a mycotoxin, such as for example aflatoxin, ochratoxin, T2, zearalanone, vomitoxin (deoxynivalenol a/k/a DON), patulin and fumonisin. Extraction is performed with use of a composition that includes a proteinaceous material, such as albumin, as an extraction agent.

METHOD FOR IDENTIFYING AND EVALUATING TOXIGENIC CAPABILITY OF AFLATOXIGENIC STRAIN

A method for identifying and evaluating toxigenic capability of an aflatoxigenic strain. A ratio of the aflatoxin yield to Nor-1 gene transcriptional quantity is determined to have high relative stability. An Aspergillus flavus strain toxigenic capability identification model is established, and thus a regression equation between the Aspergillus flavus toxigenic capability and the ratio AFT/Nor-1 of the aflatoxin yield to the Nor-1 gene transcriptional quantity is obtained.

NON-ANTIBODY LIGANDS FOR DETECTING TARGET PROTEINS

The invention relates generally to synthetic non-antibody protein scaffolds (synNAPS) that differentially detect or quantitate a target insecticidal protein in a complex biological matrix comprising the target protein and a non-target insecticidal protein and to methods of using the synNAPS in immunoassays, and more particularly to monoclonal antibodies and immunoassays for the differential detection and quantitation of a wild-type crystal protein, such as a wild-type-Cry1Ab, from Bacillus thuringiensis and hybrid crystal proteins, which comprise all or a significant portion of the wild-type Cry protein in complex biological samples comprising both the wild-type Cry protein and one or more of the hybrid Cry proteins.

ENGINEERED MICROBE-TARGETING MOLECULES AND USES THEREOF

Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. Some particular embodiments of the microbe-targeting or microbe-binding molecules comprise a carbohydrate recognition domain of mannose-binding lectin, or a fragment thereof, linked to a portion of a Fc region. In some embodiments, the microbe-targeting molecules or microbe-binding molecules can be conjugated to a substrate, e.g., a magnetic microbead, forming a microbe-targeting substrate (e.g., a microbe-targeting magnetic microbead). Such microbe-targeting molecules and/or substrates and the kits comprising the same can bind and/or capture of a microbe and/or microbial matter thereof, and can thus be used in various applications, e.g., diagnosis and/or treatment of an infection caused by microbes such as sepsis in a subject or any environmental surface. Microbe-targeting molecules and/or substrates can be regenerated after use by washing with a low pH buffer or buffer in which calcium is insoluble.
