DC67971	AF488 acid	AF 488 is a vivid green fluorescent dye. Owing to its excellent photostability, it is frequently utilized in microscopy and cell detection. AF 488 can be used in conjunction with DAPI and is highly suitable for multiplex detection. It exhibits a high quantum yield and stable fluorescence within a pH range of 4 to 10.
DC67959	Tex Red-X Acid	Tex Red-X dye is an innovative alternative to Tex Red. A key difference lies in its chemical structure - it features an additional seven - atom aminocaproyl spacer ("X") between the fluorophore and the carboxyl group. This spacer plays a crucial role in separating the fluorophore from its attachment point. By doing so, it effectively minimizes the interaction between the fluorophore and the conjugated biomolecule. One of the standout features of Tex Red - X is that it exists as a single 5 - isomer. This characteristic significantly enhances the reproducibility of results, which is a highly desirable trait in scientific research and biological applications. In terms of optical properties, Tex Red - X shares the same spectral characteristics as Texas Red. It can be utilized to create bright red fluorescent bioconjugates with excitation and emission maxima at approximately 595/615 nm. These bioconjugates are valuable tools in various biological and biochemical studies, enabling researchers to visualize and analyze biological processes with high precision.
DC67951	Tex Red-X NHS	Tex Red-X NHS is a derivative of Texas Red (HY-101878), an amphoteric rhodamine red fluorescent dye. Texas Red is widely used to study neuronal morphology and as a cell type-selective fluorescent marker for astrocytes, both in vivo and in slice preparations.
DC67950	5-TAMRA NHS	5-TAMRA NHS is an amine-reactive fluorescent agent, and its conjugate produces bright, pH-insensitive orange-red fluorescence with good photostability (Ex/Em = 565/580 nm).
DC67949	6-ROX NHS	6-Carboxy-X-rhodamine, succinimidyl ester (6-ROX, SE) is a fluorescent dye for oligonucleotide labeling and automated DNA sequencing.
DC67081	CY5-SE	Cy5-SE (Cy5 NHS Ester) is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. This dye requires small amount of organic co-solvent (such as DMF or DMSO) to be used in labeling reaction. This reagent is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling. Excitation (nm):649, Emission (nm): 670.
