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 green fluorescent CF™488A for surface staining of live cells. CF™488A is a superior alternative to the traditional green fluorescent dye FITC (or fluorescein) owing to its exceptional brightness and photostability. CF™488A has brightness and photostability comparable to Alexa Fluor® 488. Mix-n-Stain™ small ligand labeling kits for cell surface labeling are available in your choice of 10 CF™ dye colors for labeling ligands for cell surface targets, and three CF™ dye colors for ligands that bind intracellular targets.
