1,4dichloro 6carboxytetramethylrhodamine

1,4-Dichloro 6-carboxytetramethylrhodamine is a fluorescent labeling agent (Ex: 541 nm, Em: 568 nm).

(5)6-Carboxytetramethylrhodamine, a bright orange-fluorescent dye with absorption emission maxima of ~555 580 nm [1], contains a carboxylic acid that reacts with primary amines via carbodiimide activation.

1,4-Dichloro 5-carboxytetramethylrhodamine is a fluorescence labeling agent [Ex: 541 nm, Em: 568 nm].

1-(Dichloro-1,3,5-triazinyl)-pyrene (1-(4,6-Dichloro-1,3,5-triazin-2-yl)pyrene) serves as a multifunctional dye with diverse applications in both traditional and emerging fields. In biological experiments, dyes facilitate the observation and analysis of cell structures, tracking of biomolecules, evaluation of cell functions, distinction of cell types, detection of biomolecules, examination of tissue pathology, and monitoring of microorganisms. Their utilization spans from foundational scientific research to extensive clinical diagnostics. Additionally, dyes are integral to the textile industry for coloring purposes, and find innovative uses in functional textile processing, food coloring, and dye-sensitized solar cells.

The cell-permeant pH indicator, carboxy SNARF-1, acetoxymethyl ester, acetate (CAS #126208-13-7) has a pKa of ~7.5 after de-esterification, thus is useful for measuring pH changes between pH 7 and pH 8. Carboxy-SNARF-1 exhibits a significant pH-dependent

HKSOX-1, a fluorescent probe designed for the imaging and detection of endogenous superoxide in live cells and in vivo, demonstrates outstanding selectivity and sensitivity towards the superoxide anion radical [1]. For storage, it is important to protect HKSOX-1 from light.

5(6)-TAMRA contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. This bright, orange-fluorescent dye produces conjugates with absorption/emission maxima of ~555/580 nm.
