1,4dichloro 5carboxytetramethylrhodamine

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

1,N6-Ethenoadenosine 5'-monophosphate sodium (1,N6-Etheno-AMP sodium), a fluorescent analog of adenosine 5'-monophosphate (AMP), serves as an effective probe for AMP-related systems due to its detectability at low concentrations. It is characterized by an excitation wavelength range of 250-300 nm and emits at 415 nm [1] [2].

5-FAM-β-Amyloid (1-28) is a peptide labeled with a fluorescent probe, representing the initial 28 amino acids of the β-Amyloid protein.

(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-(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.

2-(Naphthalen-1-yl)-5-phenyloxazole (α-NPO) is an organic fluorescent dye featuring a nitrogen atom, potentially interacting with nitrogen introduced during the amination step [1].

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-TAMRA-Amyloid β-Protein (1-40) is a TAMRA-labeled variant of Amyloid β-Protein (1-40) with an absorption emission spectrum of 544 572 nm [1].

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.

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

5-(6)-Carboxy RhodFluor is a cell-impermeant pH indicator.

2'-Deoxy-1,N6-ethenoadenosine-5'-O-triphosphate (ε-dATP), a fluorescent derivative of 2’-deoxyadenosine-5’-O-triphosphate (dATP), promotes sister chromatid exchange in stimulated primary mouse spleen T- and B lymphocytes with LPS or concanavalin A at concentrations of 50 to 150 µM. Utilized in ambiguous base pairing investigations within vinyl chloride-induced mutagenesis research, ε-dATP, along with its related compound ε-ATP—which exhibits an emission peak at 415 nm after being excited at 300 nm—contributes to understanding genetic alterations mechanisms.
