The present invention relates to a kit of parts and methods for determining the presence and quantity of one or more TNF-α inhibitor drugs and/or anti-TNF-α inhibitor drug antibodies in one or more biological samples each comprising less than 200 μl, the method comprising the steps of providing a reaction liquid comprising the sample, a first TNF-α conjugate comprising TNF-α and a first conjugated moiety and a second TNF-α conjugate comprising TNF-α and a second conjugated moiety, said second moiety being capable of generating or ameliorating a detectable signal in the presence of a molecular complex comprising a TNF-α inhibitor, followed by detecting the change in signal when the complex between the TNF-α inhibitor drug, the first TNF-α conjugate and a the second TNF-α conjugate forms.

Cell-separation systems and methods utilizing cell-specific microbubble tags and ultrasound-based separation are described. The methods are useful for simplification of time-consuming and costly cell purification procedures and real time apoptosis detection.

Disclosed are real-time insect surveillance sensor devices and methods that use a colorimetric readout for detecting insect disease vectors (such as mosquitoes which can transmit pathogens such as DENV, CHIKV, and ZIKV). The method involves an attractive or feeding solution combined with detector conjugates. The conjugate can specifically detect proteins present in insect saliva and/or proteins specific to mosquito-borne pathogens.

An object of the present invention is to provide a kit, a method, and a reagent which prevent the problem of false positive due to nonspecific adsorption, suppress the increase in noise to be generated, and are capable of achieving high-precision measurement of a measurement target substance in a wide concentration range from a low concentration to a high concentration. According to the present invention, there is provided a kit for measuring a measurement target substance, the kit including: a first particle having a label and modified with a first binding substance; a second particle having no label and modified with a second binding substance; a flow channel for flowing the first particle and the second particle; and a substrate having a third binding substance capable of specifically binding to the measurement target substance or a substance capable of binding to the first binding substance, in which the first particle having a label is a luminescent labeled particle containing at least one kind of compound represented by Formula (1) and a particle. ##STR00001## Each symbol in Formula (1) has the meaning described in the present specification.

The invention relates to fused cyclooctyne compounds, and to a method for their preparation. The invention also relates to a conjugate wherein a fused cyclooctyne compound according to the invention is conjugated to a label, and to the use of these conjugates in bioorthogonal labeling, imaging and/or modification, such as for example surface modification, of a target molecule. The invention further relates to a method for the modification of a target molecule, wherein a conjugate according to the invention is reacted with a compound comprising a 1,3-dipole or a 1,3-(hetero)diene.

Multiplex polymeric dye devices are provided. Aspects of the devices include a solid support, and first and second dried polymeric dye compositions distinctly positioned relative to a surface of the solid support. Aspects of the invention further include methods of making and using the devices, e.g., in analyte detection applications, as well as kits containing the devices.

An indicator of a first type and an indicator of a second type are attached to a unit of a chemical component in a sample to form a first multi-indicator complex. The first multi-indicator complex includes the unit of the chemical component, the indicator of the first type, and the indicator of the second type. The indicator of the first type and the indicator of the second type have different discernible characteristics. An image of the sample, including the first multi-indicator complex corresponding to the unit of the chemical component, is captured by an image sensor. Based on a first image of the sample, a count is generated of multi-indicator complexes that include an indicator of the first type and an indicator of the second type, including the first multi-indicator complex. Based on the count, a presence or a level of the chemical component in the sample is identified.

The present disclosure discloses a detection kit and a preparation method thereof and a detection method for novel coronavirus, and relates to the technical field of biomedicine, including an antigen test strip. The antigen test strip includes a substrate, bibulous paper, immune nitrocellulose membrane, and immune microsphere pad. The immune microsphere pad, the immune nitrocellulose membrane and the bibulous paper are pasted on the substrate. The The immune microsphere pad is coated with latex microsphere-labeled novel coronavirus SARS-CoV-2 monoclonal antibody 1. The immune nitrocellulose membrane is provided with a test line coated with novel coronavirus SARS-CoV-2 monoclonal antibody 2 and a quality control line coated with goat anti-mouse IgG polyclonal antibody. The present disclosure uses latex particles as labeled tracer, and uses antigen-antibody reaction and lateral chromatography to detect and analyze targets, having advantages of convenience and swift.

Disclosed are a highly sensitive immunoconjugate, and an in vitro reagent and an in vitro diagnostic kit including the same, in which binding specificity with a target substrate is increased and a detection signal is amplified, thereby improving largely the sensitivity, accuracy and reproducibility of detection.

A test strip main body with a sample section, colloidal gold pads, an NC film and a water absorption end in sequence; and the colloidal gold pads are of 3 to 8 layers. Compared with the prior art, the test strip has higher sensitivity, which is beneficial to detection of trace or low-concentration samples.
