Methods, compositions, and kits are provided for imaging a polypeptide of interest. Methods, compositions, and kits are also provided for site-specific transcriptional regulation of one or more genetic elements.

The present invention relates to a monoclonal, pan-reactive antibody to duocarmycins. The monoclonal, pan-reactive antibody of the present invention may be used to detect, isolate and/or quantify a duocarmycin-containing antibody-drug conjugate in a biological or non biological sample, for example using an immunoassay.

A system that includes a cartridge housing and a hollow transfer module, according to an embodiment is described herein. The cartridge housing further includes at least one sample inlet, a plurality of storage chambers, a plurality of reaction chambers, and a fluidic network. The fluidic network is designed to connect the at least one sample inlet, a portion of the plurality of storage chambers and the portion of the plurality of reaction chambers to a first plurality of ports located on an inner surface of the cartridge housing. The hollow transfer module includes a second plurality of ports along an outer surface of the transfer module that lead to a central chamber within the transfer module. The transfer module is designed to move laterally within the cartridge housing. The lateral movement of the transfer module aligns at least a portion of the first plurality of ports with at least a portion of the second plurality of ports.

Processes for quantifying an amount of functional groups immobilized on a solid support are described herein. The processes allow for determining whether sufficient functional groups are provided on a solid support for the attachment of a first binding pair member for the detection of a target analyte.

A problem to be solved is to provide a glycated hemoglobin (%) assay method and assay reagent capable of accurate measurement of glycated hemoglobin (%) in blood even when a blood specimen containing hemoglobin contains abnormal hemoglobin such as HbS or HbC.

The present invention provides a method capable of accurate measurement of glycated hemoglobin (%) in blood even in a specimen containing abnormal hemoglobin by combining two types of monoclonal antibodies, i.e., an anti-glycated hemoglobin monoclonal antibody and a monoclonal antibody to the anti-glycated hemoglobin monoclonal antibody, and an assay reagent for performing the method.

Provided are devices, systems, methods and kits for determining whether a subject is immune to an infection by a disease-causing pathogen by measuring neutralizing antibodies against the disease-causing pathogen in a biological sample from the subject. The devices, systems, methods, and kits described herein are useful for confirming whether a vaccine against the disease-causing pathogen has elicited enough neutralizing antibodies to prevent a later infection, or lessen severity of disease caused by, the disease-causing pathogen. Such devices, systems, methods, and kits are also useful for detecting an infection in the subject.
