Dedication to ensure up to 3,5 months, stable blinking for dSTOM microscopy
Researchers using dSTORM imaging were constantly constrained by the short lifespan and inconsistency of standard imaging buffers. The fluorescence signals would fade too quickly, limiting the potential for long-term observation and intricate analysis.
Karine and her team, driven by his dedication to practical innovation, took on this challenge with a simple yet ambitious question: What if there was a buffer that could last up to several months after mounting, increases blinking events, stay stable, and significantly simplifies researchers workflow by limiting interruptions due to buffer renewals?
After countless experiments and refinements, the team developed EverSpark, a long-lasting buffer that revolutionizes dSTORM imaging. Designed to ensure stability over extended sessions, EverSpark provides researchers with the freedom to focus on their observations, confident in the reliability of their results.
EverSpark V2 – Pushing beyond limits with green, yellow & far-red fluorophores
With the second version of EverSpark, the improvements are game-changing. In addition to yellow and red/far-red fluorophores, this version is also compatible with green channel fluorescence signals, unlocking the potential for 3-colour dSTORM imaging. Blinking stability has been extended from two months to an incredible 3.5 months. The new formulation enhances blinking events, capturing even more crucial molecular details with greater precision. EverSpark V2 is not just an upgrade, it’s a testament to the power of continuous innovation in scientific research.
