AMPK Assay – Transcreener Application

Learn More About Transcreener Method Used for This AMPK Assay

AMPK Assay - A Transcreener ADP2 Assay Application

Transcreener ADP² Kinase Assay directly measures ADP produced by AMPK (AMP-Activated Protein Kinase). These ADP measurements allow researchers to effectively determine the activity of the AMPK enzyme. The assay provides a powerful tool to screen compound libraries for AMPK modulators to help find new therapies for disease. 

The kit comes complete with the detection reagents required to measure activity. AMPK enzyme is not included in the inhibitor screening assay kit. Please contact us for questions related to acquiring the enzyme.

This assay is designed to be used with purified enzyme preparations. Transcreener assays are not validated with cell lysates, blood, serum, or other biological samples.

How Does This AMPK Assay Work?

The Transcreener AMPK Assay determines AMPK enzyme activity by directly measuring the ADP formed by the enzyme using the Transcreener ADP Assay. By detecting ADP output, the assay provides a universal method to assess the activity of any ADP-producing enzyme in real-time.

Transcreener AMPK Assay technology uses a simple but highly effective method that consists of an antibody selective to ADP over ATP and a far-red fluorescent tracer. ADP produced in the reaction competes with the tracer changing the fluorescent properties and providing fluorescent readout.

The AMPK assay is available with FP, FI, and TR-FRET. It is a simple mix-and-read format. Perform your enzyme reaction, add the detection reagent, and measure. The simplicity of the system yields robust results that also make it extremely amiable to HTS.

Transcreener Mix and Read Assay

Robust Assay Yields Quality Data

Z’ measurements using optimized AMPK reaction conditions indicate a robust assay.  Robust data like this is vital for sizeable high throughput screens that are difficult to complete due to massive sample quantity. Both reactions have 25 μM ATP and 20 μM SAMS. Z' shown here = 0.85.

Detection of ADP Under AMPK Initial Velocity - FP Readout

The assay demonstrates linearity when raw data is converted to ADP using a standard curve. Here we use both 25 µM ATP with 20 µM SAMS peptide substrates. Linearity is shown here under initial velocity conditions when raw data is converted to ADP formed. The AMPK enzyme reaction took place for 60 minutes at room temperature. The enzymatic reaction was then halted using Stop & Detect Buffer B included in the kit and assay plates were read.

The Role of AMPK As a Therapeutic Target

AMPK is targeted for many diseases, including metabolism, inflammatory diseases, tumor suppression, and coronavirus. SARS-CoV-2 uses the ACE2 receptor to infect the human body. Research shows AMPK increases ACE2's expression and stability. Once coronavirus enters the body, it downregulates ACE2, causing a chain of events leading to deadly cardio-pulmonary issues. 

One drug currently on the market (Metformin) activates AMPK via phosphorylation. Currently used as a diabetes drug, Metformin has positive effects on both lipid and glucose metabolism via AMPK. 

Another AMPK activator AICAR has shown to improve alveolar and capillary barriers preventing damage from an infection like SARS-CoV-2 in mice. Further work needs to be done but AMPK is a target of interest for coronavirus treatment. 

The Transcreener ADP2 AMPK Assay is an excellent tool for researchers examining the therapeutic effects of AMPK.
