IKK-beta Assay – Transcreener Application

Learn More About Transcreener Method Used for This IKK-beta Assay

IKK-beta Assay - A Transcreener ADP2 Assay Application

Transcreener ADP² Assay directly measures ADP produced by IKK-beta (IKBKB, inhibitor of kappa light polypeptide gene enhancer in B-cells, or IKK2). These ADP measurements allow researchers to effectively determine the enzyme’s activity. The assay provides a powerful tool to screen compound libraries for IKK-beta modulators to help find new therapies for disease. 

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

How Does This IKK-beta Assay Work?

The Transcreener IKK-beta Assay determines IKK-beta 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 IKK-beta 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 IKK-beta 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 makes it extremely amiable to HTS.

Transcreener Mix and Read Assay

Robust Assay Yields Quality Data

Z’ measurements using optimized IKK-beta 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. Z' shown here = 0.87.

Detection of ADP Under IKK-Beta 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 15 µM IKKTide peptide substrates. Non-productive hydrolysis of ATP occurs in many kinase reactions due to many factors including autophosphorylation and water exploiting the ATP binding pocket of the enzyme.

The Role of IKK-beta As a Therapeutic Target

IKK-beta is a serine kinase in the NF-κB pathway. IKK aids in activiating NF-κB by phosphorylating a bound inhibitor IκBα, allowing NF-κB to enter the nucleus, in turn, activating various inflammatory responses. The signaling pathway is part of the innate immune response to bacterial and viral material, among other stimuli.

Incorrect regulation can lead to a number of conditions including inflammatory autoimmune disorders and cancer. Because of this, IKK-beta modulators have become emerging targets in drug discovery.

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