一般描述

Fluorescent Dye Carboxylic Acids and Their Succinimidyl Esters

Succinimidyl esters are proven to be the best reagents for amine modifications because the amide bonds that are formed are essentially identical to, and as stable as the natural peptide bonds. These reagents are generally stable and show good reactivity and selectivity with aliphatic amines.  There are few factors that need be considered when SE compounds are used for conjugation reaction: 

1). Solvents:For the most part, reactive dyes are hydrophobic molecules and should be dissolved in anhydrous dimethylformamide (DMF) or dimethylsulfoxide (DMSO). 

2). Reaction pH:The labeling reactions of amines with succinimidyl esters are strongly pH dependent. Amine-reactive reagents react with non-protonated aliphatic amine groups, including the terminal amines of proteins and the e-amino groups of lysines. Thus amine acylation reactions are usually carried out above pH 7.5. Protein modifications by succinimidyl esters can typically be done at pH 7.5-8.5, whereas isothiocyanates may require a pH 9.0-10.0 for optimal conjugations. 

3).Reaction Buffers:Buffers that contain free amines such as Tris and glycine and thiol compounds must be avoided when using an amine-reactive reagent. Ammonium salts (such as ammonium sulfate and ammonium acetate) that are widely used for protein precipitation must also be removed (such as viadinlysis) before performing dye conjugations. 

4). Reaction Temperature:Most conjugations are done at room temperature. However, either elevated or reduced temperature may be required for a particular labeling reaction.

Features and Biological Applications

TAMRA is one of the most popular fluorophores used in various bioconjugations. TMR is a bright organe fluorophore. 5(6)-TAMRA is the mixture of two carboxy tetramethylrhodamine (TMR) isomers.  It is used to modify amino and hydroxy groups using EDC-mediated couplings. It can be readily convert to the amine-reactive 5(6)-TAMRA, SE.
