General description

This labeling kit is for labeling 50-100 μg antibody with the green fluorescent dye CF488A. Mix-n-Stain CF dye antibody labeling kits are a revolutionary antibody labeling technology that permits one to label antibodies with our superior CF dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. CF488A is a green fluorescent dye optimally excitable by the 488 nm argon laser line. Under common detection settings, CF488A is similar to Alexa Fluor 488 in brightness and photostability. In microscopy or flow cytometry applications using a 520/20 filter, CF488A may appear brighter than Alexa Fluor 488 due to its shorter emission wavelength, which makes the dye optically more compatible. The shorter wavelength of CF488A also minimizes the dye′s spill-over into longer wavelength channels, making the dye advantageous in multi-color detection. Like Alexa Fluor 488, CF488A is highly water soluble, but is not as excessively negatively charged. As a result, antibody conjugates prepared from CF488A retain excellent specificity to ensure high signal-to-noise ratio.

Application

Mix-n-Stain CF 488A Antibody Labeling Kit (50-100μg) has been used in antibody conjugation and to conjugate pSMAD5 and Nkx6.1.

Features and Benefits

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.

Components

The kit consists of 1 vial each of Mix-n-Stain Dye, Mix-n-Stain Reaction Buffer (10x), Mix-n-Stain Storage Buffer, and an ultrafiltration vial.
