Piezoelectric plate sensor and uses thereof
A piezoelectric plate sensor comprising a piezoelectric layer; two electrodes; and an insulation layer. The insulation layer is produced by soaking the piezoelectric layer and two electrodes in a mercaptopropyltrimethoxysilane solution with an amount of water from 0.1 v/v. % to about 1 v/v % and at pH from about 8 to about 150 for a period from about 8 to about 15 hours, and the mercaptopropyltrimethoxysilane solution has a concentration of mercaptopropyltrimethoxysilane from about 0.01 v/v % to about 0.5 v/v %. A method of detecting a biomolecule in a sample using the piezoelectric plate sensor in particular, that of detecting a genetic marker with PCR sensitivity and specificity without the need of DNA isolation or amplification is also provided. The piezoelectric plate sensor may be used to diagnose various diseases including breast cancer, myocardial infarction, diarrhea, Clostridium difficile infection, and hepatitis B infection.
LIGAND FUNCTIONALIZED POLYMERS
Ligand functionalized substrates, methods of making ligand functionalized substrates, and methods of using functionalized substrates are disclosed.
COMPOSITION FOR ENZYME IMMUNOASSAY USING IMMUNOFLUORESCENCE AND USES THEREOF
A composition for enzyme immunoassay using immunofluorescence comprises (i) a fluorogenic enzymatic substrate and (ii) a quenched fluorogenic compound that forms a fluorescent compound after hydrolysis of the fluorogenic enzymatic substrate. The composition may be useful for performing a method for in vitro detection and/or quantification of an analyte of a liquid test sample liable to contain the analyte.
GRAPHENE-MODIFIED ELECTRODES
The specification provides an assay electrode including a composite containing a matrix and a multiplicity of graphene particles dispersed therein.
METHOD FOR THE IMMOBILIZATION OF BIOMOLECULES
The invention relates to a method for the immobilization of biomolecules containing at least one sulfhydryl group, which method comprises contacting a modified metal surface with the biomolecule irradiating the resulting surface with UV radiation in the presence of a photo-initiator, wherein said metal surface is modified with a cross-linker compound comprising a terminal thiol or dithiol group covalently linked to the metal surface, a spacer group, which at the other terminal end is carrying an isolated double or triple bond.
METHODS AND COMPOSITIONS FOR FLUORESCENCE DETECTION
Methods and compositions for imaging and scanning Western or immunoblots are disclosed herewith.
Combination of FcγRIIB-specific antibodies and CD20-specific antibodies and methods of use thereof
The present invention relates to methods of treatment, prevention, management or amelioration of one or more symptoms of diseases or disorders associated with CD20 expression that encompass administration of a combination of: (A) one or more antibodies that specifically bind FcγRIIB, particularly human FcγRIIB, with greater affinity than said antibodies bind FcγRIIA, and (B) one or more antibodies that specifically bind to CD20. Such methods include methods of treating, preventing, managing or ameliorating one or more symptoms of a B cell related disease or disorder or an inflammatory disorder. The invention also provides pharmaceutical compositions comprising an anti-FcγRIIB antibody and an anti-CD20 antibody.
QUANTITATIVE LATERAL FLOW ASSAY
The present invention relates to devices, kits, instruments and methods for quantitatively detecting multiple analytes in a sample. More specifically, the present invention relates to devices, kits, instruments and methods for quantitatively detecting multiple analytes with desired or targeted precision, and the uses thereof.
