Ready to use in just 90 minutes, our protein labeling kits include an easy-to-use, pre-packed spin column for rapid dye removal and typical recovery greater than 85%. Each kit contains enough reagent for 3–5 protein conjugation reactions.

Thermo Fisher Scientific Protein Labeling Kits provide an easy way to covalently label 1–10 mg protein MW range 20–150 kDa with a fluorescent dye (including Alexa Fluor dyes). The Protein Labeling Kits utilize an amine-reactive fluorophore to covalently attach the label to …

Microscale Protein Labeling Kits provide a convenient means for attaching a fluorescent label to a small amount of antibody or protein (20–100 μg). The kits are available in four Alexa Fluor™ colors (or biotin) and supply everything needed for three labeling and separation reactions.

Protein labeling kits from AnaSpec include Biotin, fluorescent dye, fluorescent protein, TR-FRET: all together twenty one AnaTag™labeling kits.

Efficient, easy-to-use kits for labeling antibodies and other proteins with our superior CF® Dyes and other labels. Mix-n-Stain™ antibody labeling kits dramatically simplify the process of antibody labeling. The resulting conjugates perform comparably to pre …

Elabscience ® offers a range of labeling kits that provide flexibility in labeling and excellent results. It can offer fluorochrome labeling, biotin labeling, and BSA removal kits to meet your needs for experimental reagents during the labeling …

Atto 550, which is similar to Cy3, may be useful in applications such as fluorescence resonance energy transfer (FRET) and as a tag for molecules such as secondary antibodies. Atto 550 Protein Labeling Kit contains Atto 550 succinimidyl ester which enables conjugation of Atto 550 to the primary amino groups of the proteins and other molecules.
