Description
SNAP-Cell 505™ is a photostable green fluorescent substrate that can be used to label SNAP-Tag™ fusion proteins inside living cells, on cell surfaces, or in vitro. This cell-permeable substrate (BG-505) is based on the Dyomics dye DY-505 and is suitable for standard fluorescein filter sets. It has an excitation maximum at 504 nm and an emission maximum at 532 nm. This package contains 50 nmol of BG-505 substrate, sufficient to make 10 ml of a 5 µM SNAP-tag fusion protein labeling solution.
