E2-Crimson
New • Bright • Fast-Maturing • Far Red
Far red fluorescent proteins are ideal for live-animal imaging because absorption and light scattering are relatively low in tissues at wavelengths above 600 nm.
E2-Crimson:
- Is brighter than other far red fluorescent proteins
- Matures substantially faster than other red and far-red fluorescent proteins
- Displays low cytotoxicity in bacterial and mammalian cells
- Has the furthest red-shifted excitation of any known GFP homologue (611 nm), which makes it the first fluorescent protein that is efficiently excited with standard far-red lasers.
