mEmerald Fused to Human Alpha-Tubulin

mEmerald Fused to Human alpha-Tubulin

The cytoskeletal components called microtubules are formed from monomeric proteins known as tubulin. Each tubulin subunit is a heterodimer composed of alpha-tubulin and beta-tubulin components linked together by noncovalent bonds. To produce the image featured above, human alpha-tubulin was visualized when fused with mEmerald, a green variant of EGFP having improved photostability and brightness. The peak excitation and emission wavelengths of mEmerald are 487 and 509 nanometers, respectively.
