Mix-n-Stain™ CF™ Dye Antibody Labeling Kits
Covalently label 5 to 100 ug of an Antibody with the Brightest Dyes in 30 min — It’s a Revolution!
Mix-n-Stain™ CF™ dye antibody labeling kits dramatically simplify the process of preparing fluorescently labeled antibodies, particularly primary antibodies. Simply mix your antibody with a CF™ dye of your choice in the buffer provided, a step that takes less than 30 seconds of hands-on time. After waiting for another 30 minutes, without a separation step, you will have a fluorescent antibody conjugate that is as good as the best pre-labeled fluorescent antibody you can buy from some of the leading suppliers. There is no need to calculate how much dye you should use; just mix your antibody with the entire amount of dye provided and you will always produce optimal labeling. Moreover, the labeling reaction can tolerate the presence of common stabilizers, such as sodium azide, Tris, glycerol and low level of BSA.
Another major advantage of the labeling kits is our superior CF™ dyes, many of which are brighter and more photostable than Alexa Fluor® dyes and other similar commercial dyes. With a large list of CF™ dyes of wavelengths covering the entire visible and near-infrared spectra, you have unprecedented freedom to label any commercial primary antibody with a color of your choice, making multi-color detection simple and affordable.

Frequently Asked Questions and Answers:
Q: Is the labeling chemical or physical?
A: The labeling is chemical, which means the dye is covalently attached to the antibody. Covalent labeling ensures no dye transfer or diffusion in multi-color detection employing multiple antibodies labeled with different CF Mix-n-Stain kits.

Q: What are the advantages of Mix-n-Stain kits over Invitrogen’s Zenon antibody labeling kits?
A: There are four major advantages: 1) the CF dye is covalently attached to the antibody to eliminate dye transfer or diffusion between antibodies during multi-color staining; 2) Mix-n-Stain conjugates are stable for several months in storage buffer whereas Zenon labeling reagents are required to be used within 30 minutes; 3) Mix-n-Stain conjugates are less bulky because the dyes are directly linked to the antibody, unlike Zenon conjugates which use antibody fragments or other linkers; 4) No dye/protein optimization is needed, just mix and then stain.
