CF® Dye Succinimidyl Ester
CF® Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues.
Anhydrous DMSO (dimethyl sulfoxide; methyl sulfoxide) is recommended for preparing stock solutions of AM ester dyes, reactive dyes and other related moisture-sensitive products.
CF® Dye & Biotin SE Protein Labeling Kits
This kit contains everything you need to label antibodies or other proteins with a fluorescent CF® dye succinimidyl ester (CF® dye SE) or biotin succinimidyl ester (biotin SE). Each kit contains reagents for three labeling reactions of up to 1 mg protein per reaction.
TRITC, 5 and 6 isomers
Free acid form of 5-TAMRA (5-Carboxytetramethylrhodamine, single isomer).
Carboxyrhodamine 110-X succinimidyl ester, 5 and 6 isomers
5-(and-6)-Carboxyrhodamine 110-X, succinimidyl ester (5(6)-CR 110-X, SE) readily couples to a primary or secondary amine. The dye is a superior alternative to 5(6)-SFX because of its exceptional phototostability and fluorescence insensitivity to pH (4-9).
