Abstract: A multi-tenant, RFID system that may be Cloud based or run on a local area network (LAN) for distributed RFID devices and RFID applications. The RFID system a central abstraction and translation layer between RFID devices installed in geographically diverse locations and applications. RFID devices initiate communication to a Cloud or LAN network over to send events and receive commands. RFID applications can receive RFID tag data, device health, and requested and derived events from the RFID system to automatically run processes based on the provided data. Applications manage RFID devices and settings in the RFID system using command and configuration interfaces.

Abstract: Disclosed herein are compositions and methods for stabilizing a benzothiazole luciferin analog such as D-luciferin and 6-amino-D-luciferin. The compositions may include the benzothiazole luciferin analog, a thionucleobase compound of formula (I), and a liquid medium, in which the thionucleobase is present in an amount effective to stabilize the luminogenic composition against decomposition. The methods provided herein may stabilize the benzothiazole luciferin analog against decomposition by contacting the benzothiazole luciferin analog with an effective amount of the thionucleobase compound in the presence of a liquid medium. Also provided herein is a kit containing the composition.

Abstract: Provided herein are methods for the real-time monitoring of an intracellular event or response. In particular, the methods provided herein monitor the conversion of a pro-substrate to a substrate for a protein sensor as a result of an intracellular event or response.

Abstract: A mutant hydrolase optionally fused to a protein of interest is provided. The mutant hydrolase is capable of forming a bond with a substrate for the corresponding nonmutant (wild-type) hydrolase which is more stable than the bond formed between the wild-type hydrolase and the substrate. Substrates for hydrolases comprising one or more functional groups are also provided, as well as methods of using the mutant hydrolase and the substrates of the invention. Also provided is a fusion protein capable of forming a stable bond with a substrate and cells which express the fusion protein.

Also described are methods of making the compounds, such as a method using aminopyrazine acetophosphonates as synthesis intermediates.

Abstract: A system includes a processor, a barcode reader, and an RFID R/W component. The barcode reader scans a barcode of an item to generate barcode information, and communicates the barcode information to the processor. The RFID R/W component receives, from the processor, a serialization number corresponding to the barcode information. The RFID R/W component then writes the serialization number to an RFID tag of the item.
