Semrock Filter Set: TxRed-4040C

BrightLine® single-band filter set, optimized for Texas Red and other like fluorophores

This filter set is ideal for use with Texas Red® and other red fluorophores, including the monomeric fluorescent protein mCherry. It also works well for broader orange-to-red fluorophores like MitoTracker Red. It is optimized to provide the highest brightness, while maintaining a very high signal-to-noise ratio.

Individual filters and filter sets (no cube):
These filters sets contain individual filters. For filter sets already mounted in a holder/cube, scroll down to see complete mounted sets with cubes.
