Light-up RNA aptamers or Fluorescent light-up aptamers (FLAPs) are a genetically-encoded RNA imaging platform. They are designed to bind specific fluorogenic dyes that 'light-up' only in the bound state. This property of 'fluorogenicity' means that fluorescence can be 'switched on' upon RNA expression. Light-up aptamers can be thought of as the RNA counterpart to fluorescent proteins, such as GFP. Commonly used light-up aptamers include Spinach, Mango, Corn and Broccoli, named for their vibrant colors.

Bioluminescent substrates are commonly utilized for non-invasive monitoring of biological processes, for example in bioluminescence imaging (BLI) in both in vivo and in vitro settings. Luciferase substrates emit light when they become oxidized, which can be detected using fluorescence microscopy.

BromoCatch^™ is a new, versatile self-labelling protein (SLP) tag platform for efficient protein analysis and live cell imaging.

Photolysis is an experimental tool that enables the release of ligands adjacent to their receptors, overcoming the effects of diffusion that will otherwise dominate the kinetics of the receptor activation. It requires photolabile precursors of relevant ligands, known as caged compounds.

Tocris offers a broad range of fluorescent and bioluminescent reagents, to facilitate the visualization of sub-cellular components in live and fixed cells with high sensitivity and selectivity. The product range includes fluorescent probes, dyes and indicators.

Fluorescent probes for imaging bacteria are useful for advancing bacterial research and antibiotic design. One technique for studying bacteria, is to incorporate fluorescent probes such as Fluorescent D-amino acids (FDAAs) into the cell wall of live bacteria. FDAAs are suitable for use with confocal and super-resolution microscopy (SRM).

The Janelia Fluor^® Haloalkane dyes are cell-permeable fluorogenic dyes with a chloroalkane handle. They covalently bind to HaloTag^® self-labeling protein which can be used for tagging a protein of interest. Several of these dyes show a high degree of fluorogenicity following binding to the HaloTag protein, enabling wash-free imaging. They are suitable for use in live-cells, tissues and in vivo imaging, and are especially well suited to super-resolution microscopy (SRM) techniques.
