The pNPP (p-NitroPhenyl Phosphate) liquid, ready-to-use substrate is a highly active and stable formulation utilized for measuring AP- (Alkaline Phosphatase) probe activity. The solution is a solvent free buffer solution containing stabilized pNPP using sodium azide as preservative. In kinetic assays p-nitrophenol appears yellow and is measured at 405 /650 nm. If stopped reactions are preferred, add equal amounts of 1 .0 M s…
The liquid BCIP/NBT is the most commonly used substrate for colorimetric determination of Alkaline Phosphatase (AP) activity in membrane tests. We offer an aqueous buffered solution containing NBT (NitroBlue Tetrazolium) and BCIP (Bromo-Chloro-Indolyl Phosphate) forming a blue/purple precipitate at the positive sites. The colour develops when AP catalyses the dephosphorylation of BCIP. The intense blue/purple precipitate is…

The Sirocco™ plates are the most technologically advanced protein precipitation plates in the market and enable high-throughput “in-well” protein precipitation of biological samples without the fear of cloudy filtrates or clogged devices. It also provides optimum performance in faster processing time by reducing steps in ‘in-well’ sample processing and complete recovery of clean filtrate from smaller plasma sample volumes.
Alpha is a bead-based, no-wash luminescent technology. When Alpha Donor and Acceptor beads are brought together through binding to target, a cascade of chemical reactions is set in motion, creating an amplified signal. These versatile beads are conjugated with various biomolecules that enable detection of unique biological events, offering maximum flexibility.
In 2008 Gentronix launches a new S9 protocol to extend the application of the GreenScreen HC assay to include the detection of genotoxic metabolites. Many pharmaceuticals only present a genotoxicity hazard after metabolism and such chemicals are called pro-mutagens or pro-genotoxins. Generally, although not exclusively, the liver is considered responsible for the “metabolic activation” (MA) of promutagens. However, none of t…

SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction. SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.
Cation-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid. Note that Cation-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The functional group imparts selectivity for cationic analytes, such as primary, secondary and tertiary amines.
3M Bioanalytical Anion-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with quaternary ammonium groups.
