Assay Solutions for Your Toughest Targets

BellBrook Labs offers cutting-edge assays to meet the demanding needs of drug discovery researchers. Leveraging our Transcreener and AptaFluor Assay platforms, our scientists continuously work to validate and develop assays ready for your most challenging enzyme targets. 

Our assay systems include the enzyme, substrate, assay plates, and buffers required for the respective Transcreener or AptaFluor Assay, providing a complete assay solution to simplify your discovery process. 

Cut your development time from months to days!

Transcreener Assay Technology

Transcreener Assay Overview

Transcreener technology uses a simple but powerful method that consists of antibodies selective to nucleotides and far-red fluorescent tracers. The product produced in the reaction competes with the tracer, changing the fluorescent properties and providing a readout.

Transcreener is a simple mix-and-read format. Perform your enzyme reaction, add the detection reagent, and measure. The system yields robust results that also make it extremely amiable to HTS.

AptaFluor Assay Technology

AptaFluor SAH Methylatransferase Assay Schematic

The AptaFluor SAH Methyltransferase Assay uses a naturally occurring aptamer that selectively binds SAH, the product of methyltransferase reactions.

The exquisite affinity and selectivity of the aptamer combined with a positive TR-FRET signal enable screening and profiling of methyltransferases with unparalleled sensitivity.

As a result, the AptaFluor SAH Methyltransferase Assay overcomes technical gaps of current detection methods that are not sensitive enough for enzymes with low turnover or high SAM affinities.

Enzolution™ Assay Systems
