In the field of targeted protein degradation, particularly in the development of molecular glue drugs targeting the critical transcription factor BCL6, the ability to rapidly and accurately quantify the efficiency of candidate compounds in inducing ternary complex formation is a key step in accelerating lead compound discovery and optimization.
To address this need, we present the Human BCL6/CRBN PROTAC Binding Kit. This kit utilizes advanced homogeneous time-resolved fluorescence (TR-FRET) technology, specifically designed for quantitative detection of molecular glue (e.g., ARV-393)-mediated inducible interactions between the DDB1/CRBN E3 ubiquitin ligase complex and BCL6 target protein, providing a powerful tool for high-throughput screening and mechanistic studies.
I. Core Principle: Direct "Visualization" of Protein Complex Assembly
This kit employs a homogeneous, wash-free detection format, directly reporting ternary complex formation through sensitive TR-FRET signals.
Intelligent Detection Design: The kit provides Eu-labeled donor antibodies and acceptor-labeled receptor antibodies, which specifically recognize different tags on the DDB1/CRBN complex and BCL6 protein, respectively.
Key to Signal Generation: When an effective molecular glue (e.g., ARV-393) is present in the sample, it acts as a "bridge," inducing close spatial proximity between DDB1/CRBN and BCL6, thereby bringing the corresponding donor and receptor antibodies into close proximity.
From Energy Transfer to Specific Signal: When the donor Eu is excited by a specific light source, its energy is efficiently transferred to the nearby acceptor via fluorescence resonance energy transfer (FRET), ultimately generating a long-lived specific fluorescence signal at 665 nm. The intensity of this signal is directly proportional to the amount of ARV-393-mediated ternary complex formation, enabling precise quantification.
II. Why Choose This Kit? Core Advantages at a Glance
| Advantage Dimension | Limitations of Traditional Methods | This Kit's Solution |
|---|---|---|
| Workflow | Multi-step, requires washing (e.g., ELISA, Pull-down), time-consuming and labor-intensive, low throughput. | Truly homogeneous detection, "add-mix-incubate-read," no washing steps required, extremely simple operation, automation-friendly. |
| Detection Quality | Susceptible to interference from short-lived fluorescence in sample matrices, low signal-to-noise ratio. | Time-resolved detection, delayed measurement effectively subtracts background interference, delivering ultra-high signal-to-noise ratio and stable, reliable data. |
| Throughput and Cost | Difficult to perform large-scale compound screening. | Perfectly compatible with 384-well or 1536-well plates, optimized for high-throughput screening (HTS), significantly saving precious samples and reagent consumables. |
| Information Dimension | Typically only endpoint binding data. | Enables real-time kinetic monitoring, in-depth assessment of compound-induced binding rates and strength. |
III. Broad Application Scenarios
High-throughput screening of BCL6-targeting molecular glues/PROTACs: Rapidly discover novel active molecules capable of inducing CRBN-BCL6 binding from large compound libraries.
