Description
SNAP-Surface 549 ™ is a photostable fluorescent substrate that can be used to label SNAP-tag™ fusion proteins in solution or on the surface of living cells. This cell impermeable substrate (BG-549) is based on the Dyomics dye DY-549 and is suitable for use with standard TAMRA or Cy3 filter sets. It has an excitation maximum at 553 nm and emission maximum at 566 nm. This package includes 50 nmol of SNAP-Surface 549, sufficient to make 10 ml of a 5 µM SNAP-tag fusion protein labeling solution.
