Protein Quantification Protein Labeling Kits Products & Reviews

Easily label SNAP-tag®, CLIP-tag™, HaloTag®, or other ligands with fluorescent dyes, no purification needed. Cell membrane-permeant and impermeant dye options for intracellular or surface targets.

Label 5-50 ug of VHH (also known as Nanobodies®) containing a single free cysteine with Biotium’s bright and photostable CF® Dyes, with no purification after labeling.

Label your IgG antibody with one of our superior CF® Dyes in as little as 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

Label your IgM antibody with one of our superior CF® Dyes in 15-30 minutes without a purification step.

These kits allow optimal labeling of single-chain nanobodies with CF® dyes or biotin in 30 minutes without a purification step.

Label your antibody with one of our CF® Dyes specialized for STORM super-resolution microscopy. Labeling takes just 30 minutes without a purification step, and yields an antibody conjugate with a low degree of labeling optimal for STORM.
