Avicor’s highly effective fluorophore AC-202 in Biotechnologies for Biofuels Journal

Researchers at Aix-Marseille University (France) demonstrated that our new, blue fluorescent dye, AC-202 is effective in both green algae Chlamydomonas reinhardtii and pennate diatom Phaeodactylum tricornutum. They also  prooved that after minimal sample preparation, it can label lipid droplets induced by nitrogen starvation or by inhibitors of the TOR (target of rapamycin) kinase. They found that AC-202 benefits from a low background signal and is therefore more sensitive than BODIPY for semiquantitative in vivo fluorescence measurements. Finally, a co-staining experiment indicated that AC-202 can be used for multicolor imaging in combination with both red and green fluorophores.

It has been concluded that AC-202 is an alternative and highly effective fluorophore for algal research that resolves drawbacks encountered with other neutral lipid dyes. AC-202 can be used to rapidly and sensitively visualize lipid droplets, and will contribute to the identification of metabolic and signaling pathways involved in lipid droplet formation, monitoring lipid production, and in the development of screens for algal strains suitable for biofuel production.
