To enable researchers to quickly and easily begin using our protein labeling system, our Starter Kits include all the components necessary to covalently attach either a red or a green fluorophore to SNAP-tag®, CLIP-tag™ or ACP-tag fusion proteins in living cells, fixed cells or in vitro. Each Starter Kit contains a plasmid encoding the tag of interest and two cell permeable or non-cell permeable fluorescent labels. A positive control plasmid encoding a tagged protein with a well-characterized sub-cellular localization is also included (e.g., membrane, nucleus, etc.). Where available, a negative control blocking agent is included that interacts with the tag of interest, but is non-fluorescent.
