Description
SNAP-Biotin™ is a cell-permeable substrate (BG-Biotin) based on biotin with an amidocaproyl linker. It is suitable for applications such as biotinylation of SNAP-tag™ fusion proteins in living cells for detection with streptavidin fluorophore conjugates or labeling in solution for analysis by SDS-PAGE/Western Blot or for capture with streptavidin for binding and interaction studies. This package contains 50 nmol of SNAP-Biotin substrate, sufficient to make 2.5 ml of a 20 µM solution for the labeling of SNAP-tag fusion proteins in cells.
