Description
SNAP-Cell 430 is a blue 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-430) is based on diethylaminocoumarin and is suitable for appropriate blue lasers and filter sets. It has an excitation maximum at 421 nm and emission maxima at 444 and 484 nm. This package includes 50 nmol of SNAP-Cell 430 substrate, sufficient to make 10 ml of a 5 µM SNAP-tag fusion protein labeling solution.
