Sigma Aldrich Fine Chemicals Biosciences Sera MagTM SpeedBeadsTM Pr

Sera-Mag(TM) SpeedBeads(TM) and Sera-Mag(TM) Carboxylate-Modified Magnetic Particles combine a fast magnetic response time and high binding capacity with a large surface area high sensitivity stability physical integrity and fast reaction kinetics. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag(TM)) or two (Sera-Mag(TM) SpeedBeads(TM)) layers of magnetite are then coated onto this core while the surface is modified to minimize non-specific binding of proteins.

Sigma Aldrich Fine Chemicals Biosciences TranscreenerR UDP2 TR FRET10k

The Transcreener(R) UDP2 TR-FRET Red Assay is a competitive immunoassay for UDP with a far-red time-resolved Foumlrster-resonance-energy-transfer (TR-FRET) readout. Because it is highly selective for UDP the assay can be used with any enzyme that generates UDP from a UDP-sugar donor. Examples include glycosyltransferase galactosyltransferase glucuronyltransferase N-acetylglucosamyltransferase N-acetylgalactosyltransferase xylosyltransferase and glycogen cellulose lactose and hyaluronan synthases. The Transcreener(R) assay is designed specifically for high-throughput screening (HTS) with a single-addition mix-and-read format. It offers reagent stability and compatibility with commonly used multimode plate readers. The generic nature of the Transcreener(R) HTS assay platform eliminates delays involved in assay development for new HTS targets and greatly simplifies compound and inhibitor profiling across multiple target families. The Transcreener(R) UDP2 TR-FRET Red Assay pro
