Abstract: The subject invention provides a site-specific integration system and methods for generating eukaryotic cells lines for protein production. The provided system includes a first site-specifically integrating target vector and a second site-specifically integrating donor vector comprising a gene of interest. Also provided are mammalian cell lines produced by the subject methods and systems, as well as kits that include the subject systems.

Abstract: The present invention provides a test strip with an expanded dynamic range for performing an assay to determine the presence of, or measure the quantity of, an analyte in a sample. It also provides methods for determining the presence of, or measuring the quantity of, an analyte in a sample, and for detecting a prozone sample.

Abstract: Devices, systems, and methods for detecting the presence of one or more analytes in a sample are described. In some variations, a test strip may be used to detect and/or analyze one or more analytes in a sample. In certain variations, a test strip configured to receive a sample for detection of an analyte therein may comprise a substrate and a coating on a portion of the substrate, the coating comprising a combination of a first analyte capture agent configured to bind to a first analyte and a second analyte capture agent configured to bind to a second analyte that is different from the first analyte.
