Sulforhodamine 101 (Texas Red®)-PEO3-Amine
Sulforhodamine 101-PEO3-amine has a long water-soluble spacer separating the dye and the amine group. The dye can be coupled to activated carboxy groups or sulfonyl chlorides.

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.
CF® Dye Aminooxy
Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent.
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.
EDC (or EDAC) (1-(3-Dimethylaminopropyl-3-ethylcarbodiimide, hydrochloride)) has recently been found to be very useful for fixing in situ chelators, including the fluorescent ion indicators for histological studies following physiological experiments. EDC is also a widely used reagent to activate carboxy groups for amine coupling.
