Mix-n-Stain small ligand labeling kits are designed for rapid labeling of low molecular weight (MW approx. 150 -5000) and relatively high affinity biological ligands (or substrates) without a purification step. The ligand to be labeled must contain an aliphatic amine group that is biologically inert. The amino group will form a covalent linkage with the provided reactive CF dyes. For example, suitable ligands or substrates include SNAP-tag, CLIP-tag and HaloTag ligand derivatives that have an aliphatic amine. For more information, please download the Mix-n-Stain small ligand labeling kit flyer and the product information sheet for this product.
This kit is for labeling the small ligand with blue fluorescent CF408 for intracellular staining of live cells.
