The Role of LED Illumination in High Content Screening
At the heart of every high content screening system is a fluorescence light source, and LEDs offer many advantages.
When it comes to High Content Screening (HCS), widefield fluorescence is an essential tool for biomedical applications
such as drug discovery, toxicity testing, and disease modelling. And at the heart of effective HCS is the fluorescence light source.
Fluorescence Microscopy in High Content Screening (HCS)
In High content Screening setups, fluorescence microscopy complements traditional brightfield analysis by allowing the detection and quantification of fluorescently labelled targets within cellular samples.
This dual approach enhances the accuracy and relevance of HCS assays, leading to more robust experimental results and better-informed decisions.
Choosing the Best Light Source for HCS
The success of fluorescence microscopy in HCS heavily depends on the choice of light source to illuminate the sample. Historically, widefield fluorescence illumination relied on mercury or metal halide lamps. However, these traditional light sources had several drawbacks, including frequent bulb replacements, spectral variability and the use of toxic mercury.
The advent of LED technology has addressed these issues, offering more efficient, reliable, and customisable light sources for HCS applications. LEDs provide several advantages over traditional light sources:
- High-Speed Acquisition: The high power of LEDs enables rapid imaging with high frame rates, allowing researchers to scan through large sets of cellular samples quickly and efficiently.
- Superior Image Quality: LEDs produce discrete spectra that can be precisely matched to the fluorophores used in HCS assays. This results in higher signal-to-noise ratios and improved image clarity compared to broad-spectrum light sources.
- Longevity and Stability: LEDs have a longer lifespan and maintain consistent performance over time. This not only achieves precise imaging data, but also reduces the need for frequent replacements and minimises downtime in high content imaging workflows.
