GFP single band Fluorescence Filter Set

The green fluorescent protein ( GFP ) is a protein composed of 238 amino acid residues that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. It is can be excited by the 488 nm laser line and is optimally detected at 510 nm. The biggest advantage of GFP is that it can be heritable, depending on how it was introduced, allowing for continued study of cells and tissues it is expressed in. Visualizing GFP is noninvasive, requiring only illumination with blue light. To date, GFP has been expressed in many species, including bacteria, yeasts, fungi, fish and mammals, including in human cells.
