Green-to-red primed conversion of Dendra2 using blue and red lasers

Abstract

Recently, an unusual phenomenon of primed conversion of fluorescent protein Dendra2 by combined action of blue (488 nm) and near-infrared (700–780 nm) lasers was discovered. Here we demonstrate that primed conversion can be induced by red lasers (630–650 nm) common for most confocal and single molecule detection microscopes.
