SNAP-Surface® 594 is a photostable fluorescent substrate that can be used to label SNAP-tag® fusion proteins in solution or on the surface of living or fixed cells

This substrate (BG-594) is based on the ATTO-TEC dye ATTO 594 and is suitable for standard Texas Red and Alexa 594 filter sets. It has an excitation maximum at 606 nm and emission maximum at 626 nm. This package includes 50 nmol of SNAP-Surface 594 substrate, sufficient to make 10 ml of a 5 µM SNAP-tag fusion protein labeling solution.
