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

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.
