The present disclosure related to a method of detecting a molecule using an antibody-DNA conjugate, and pharmaceutical compositions comprising new polypeptides and use thereof.

The present disclosure is directed to antibodies binding to enterovirus D68 (EV-D68) and methods for use thereof.

A biosensor for detection of a target substance in a sample with impedance spectroscopy or impedance measurement on a single frequency.

A pathogen detection apparatus includes a collector that collects a pathogen in air; a reactor that causes the pathogen collected by the collector to react with a labeled substance; a time measurer that measures time from start of reaction in the reactor; a detector that detects a quantity of labeled substance that has reacted with the pathogen; and a controller. The controller calculates a gradient value on the basis of a predetermined time period from the start of reaction measured by the time measurer and the quantity of labeled substance detected by the detector, and determines, on the basis of the gradient value, a time interval to next collection that is to be performed by the collector.

Compositions and methods for determining the efficacy and/or potency of a vaccine preparation are described herein. Splenocytes from immunized animals are isolated and frozen. Upon thawing aliquots these cells are activated by exposure to a series of dilutions of q vaccine preparation being tested and a series of dilutions of a reference vaccine with known characteristics. Cells secreting immunogen-specific antibody and cells secreting nonspecific antibody are enumerated, as is the amount of immunogen-specific and nonspecific antibody produced. Comparison between the results from the vaccine preparations provides a measure of relative vaccine efficacy and/or potency.

The present disclosure is directed to antibodies binding to and neutralizing the coronavirus designated SARS-CoV-2 and methods for use thereof.

A method for generating progeny of an African swine fever (ASF) virus includes providing an isolated or purified fetal porcine lung alveolar macrophage cell capable of replicating the ASF virus, wherein the cell is cultured for at least 5 passages; exposing the cell to the ASF virus; and allowing the ASF virus to replicate in the cell; thereby generating progeny of the ASF virus.

The present invention relates to a method of elevating prediction accuracy of grouping subjects with severe dengue infection. In the method, a non-structural protein 1 (NS1) and an endogenous anti-NS1 antibody of dengue virus in an ex vivo biological specimen are detected and crossly compared, leading in reduce of false negative rates of testing results, as well as elevating grouping accuracy of patients with severe dengue infection.

A molecular electronics sensor capable of performing genetic analysis is described. In various embodiments, the sensor comprises spaced-apart electrodes, a bridge molecule coupled to the electrodes, and an oligonucleotide hybridization probe conjugated to the bridge molecule. The hybridization probe may comprise an oligonucleotide sequence complementary to a segment of a pathogen genome to be detected. In various aspects, a plurality of such sensors are disposed as an array of pixels on a CMOS chip. Sensors herein can be configured to detect a segment of SARS-CoV-2 genome in a bio-sample.

The present invention provides systems, devices, and methods for point-of-care and/or distributed testing services. The methods and devices of the invention are directed toward automatic detection of analytes in a bodily fluid. The components of the device can be modified to allow for more flexible and robust use with the disclosed methods for a variety of medical, laboratory, and other applications. The systems, devices, and methods of the present invention can allow for effective use of samples by improved sample preparation and analysis.
