Summary
Label-free screening assays offer advantages over traditional methods by enabling temporal measurements. While promising for high-throughput screening (HTS), further elucidation of signal mechanisms is needed for wider adoption.
Area of Science:
- Biophysics
- Cell Biology
- Assay Development
Background:
- Traditional screening assays rely on reporter labels, which have inherent limitations.
- Label-free techniques offer temporal measurement capabilities to overcome these limitations.
Purpose of the Study:
- To review label-free assay approaches and their applications.
- To discuss technical challenges and the relevance of label-free assays in high-throughput screening (HTS).
Main Methods:
- Literature searches via PubMed and other sources.
- Inclusion of authors' personal experience and published books.
- Focus on label-free biophysical techniques and their application in HTS.
Main Results:
- Label-free assays are gaining traction, especially with the advent of 96- and 384-well plate systems.
- These methods are increasingly used with native cell lines, moving away from transfected cell lines.
Conclusions:
- Label-free biophysical techniques are emerging as valuable tools, complementing traditional screening platforms.
- Skepticism persists due to incomplete understanding of signal generation and biological relevance.
- Wider acceptance hinges on fully elucidating the physical basis and contextual relevance of label-free signals.
