92354 Mix-n-Stain CF640R Small Ligand Labeling Kit
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 an antibody with far-red fluorescent CF640R for surface staining of live cells. CF640R dye is brighter and far more photostable than Alexa Fluor? 647 when excited by the 633 or 635 nm laser.
