How Do Our ATPase Profiling Services Work?

Choose an ATPase Profiling Panel

BellBrook Labs offers a standard profiling panel. This panel may be customized to better meet your needs depending on the requirements. Contact us if you are interested in our standard ATPase profiling panel or a customized ATPase panel.


Choose an ATPase Target

Services are available for customers interested in a single ATPase target. If you don't see your target listed, please inquire. We are developing assays for new targets all the time. We may have experience with that target or a similar one within an enzyme family.

Overview of the Transcreener ATPase Assay for ATPase Profiling

The Transcreener ATPase Assay is a universal method to assess the activity of virtually any ATPase enzyme. The assay measures enzyme activity by directly detecting ADP formed during ATP hydrolysis.

Assay Features

  • Direct detection of unlabeled ADP
  • HTS-Ready Assay
  • Kinetic Mode Capable
  • Robust Assay Z'>0.7 under initial velocity conditions
  • Far-red fluorescent readouts minimize compound interference
  • A safe, non-radioactive method
  • Available in FP, FI, or TR-FRET readouts

Why Choose BellBrook Labs to Accelerate Your Program?

Leveraging BellBrook's services expertise will save you time and money. Your project will be handled by the same BellBrook scientists who developed the Transcreener assay and have optimized them for more than 100 different enzymes, including kinases, ATPases, GTPases, glycosyltransferases, ligases/synthetases, and phosphodiesterases. We will tailor our efforts to meet your specific needs. For example, minimizing consumption of limited reagents or enabling simultaneous screening for inhibitors and activators. And we will work fast. If your target enzyme is in good shape, we can generally complete the services within two to four weeks.

Case Study: Probing p97 ATPase with the Transcreener ADP2 ATPase Assay

p97 ATPase acts on diverse substrate proteins to partake in various cellular processes such as membrane fusion and endoplasmic reticulum-associated degradation (ERAD). The customer was expressing two different p97 enzyme preparations - Human and Mouse - but they had been unable to detect activity with the methods they were employing. The two preparations of the enzyme were provided to BellBrook under a materials transfer agreement and an experimental plan was developed as per the customer needs.  

The goals of this study were to:

  1. Evaluate the activity of the two enzyme preparations and determine the optimal enzyme concentration to be used for an HTS assay.
  2. Determine which of the two detection modes, FP or TR-FRET, would be most suitable for this project.

BellBrook's scientific team optimized enzyme reaction and detection conditions that produced outstanding assay windows and Z' values for both forms of the enzyme within one week.
