DC67979	ATO 532	ATO 532 Acid has an identical molecular structure to ATTO 532 Acid. It is a fluorescent label related to the well - known dye Rhodamine 6G. This dye is characterized by strong absorption, a high fluorescence quantum yield, excellent thermal and photostability, and good water solubility. Thanks to these features, ATO 532 is highly appropriate for single - molecule detection applications and high - resolution microscopy techniques, including Photoactivated Localization Microscopy (PALM), direct Stochastic Optical Reconstruction Microscopy (dSTORM), Structured Illumination Microscopy (SIM), and Stimulated Emission Depletion Microscopy (STED). In addition, it is also very suitable for use in Fluorescence - Activated Cell Sorting (FACS) and Fluorescence In Situ Hybridization (FISH). The fluorescence of ATO 532 Acid can be most efficiently excited within the range of 515 - 545 nanometers.
DC67978	ATO 488 Acid	ATO 488 has the same molecular structure as ATTO 488. It is a new type of hydrophilic fluorescent dye that offers excellent water - solubility, strong absorption capacity, a high fluorescence quantum yield, as well as outstanding thermal and photostability. Due to these remarkable properties, ATO 488 is highly suitable for single - molecule detection applications and high - resolution microscopy techniques such as Structured Illumination Microscopy (SIM) and Stimulated Emission Depletion Microscopy (STED). Moreover, this dye is also well - suited for use in Fluorescence - Activated Cell Sorting (FACS) and Fluorescence In Situ Hybridization (FISH).
DC67977	ATO 465 NHS	The ATO 465 molecule shares the same structure as ATTO 465. It is a fluorescent dye derived from the well - known acridone dye. ATO 465 has moderate hydrophilicity. Its fluorescence can be effectively excited within the range of 420 - 465 nm. This dye has remarkable features such as strong absorption, a high fluorescence quantum yield, excellent thermal stability, and high photostability. In an aqueous solution, this dye exhibits an astonishingly large Stokes shift of 55 nm. When it comes to a solid matrix, especially under low - temperature conditions, the dye emits intense and long - lasting phosphorescence.
DC67976	ATO 425 NHS	ATTO 425 NHS ester is a new fluorescent marker based on the Rhodamine structure. It has strong absorption, high fluorescence quantum yield, high thermal stability and photochemical stability, and is suitable for single molecule detection and high-resolution microscopy. ATTO 425 NHS ester is an NHS ester derivative of ATTO 425 that can be used to label proteins or antibodies.
DC67975	ATTO 425 Acid	The ATO 425 Acid molecule is equivalent to ATTO 425. It is a novel fluorescent marker with a coumarin structure. This marker boasts several notable characteristics, including a high fluorescence quantum yield, excellent photostability, and a relatively low molecular weight.
DC67974	AF488 Cadaverine	AF 488 Cadaverine is a carbonyl - reactive structural unit. In the presence of activators like EDC or DCC, or activated esters such as NHS esters, it can be used to modify carboxyl groups through the formation of stable amide bonds. Additionally, it can serve as a polar tracer and an active dye for labeling proteins via carboxylic acid molecules.
DC67973	AF 647 NHS	AF647-NHS ester is an analog of Alexa Fluor 647 (AF647). NHS ester can covalently bind to molecules with amino groups (such as proteins, antibodies, etc.). AF647 is a far-red fluorescent dye with an excitation wavelength (λex) of 635 nm (conventional fluorescence detection)/620 nm (instantaneous detection). Storage: Protect from light.
DC67972	AF 568 Acid	AF 568 Acid shares the same chemical structure as Alexa Fluor 568 Acid. It is a bright red fluorescent dye that is optimally suited for use with the 568 - nanometer laser line. The AF 568 dye is soluble in water and is insensitive to pH values ranging from 4 to 10. AF 568 Acid represents the most cost - effective amine - reactive form for conjugating the Alexa Fluor 568 fluorophore with polypeptides.
DC67971	AF 488 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.
DC67970	Biotin-dT	Biotin - dT phosphoramidite contains a DMT (dimethoxytrityl) group, which enables quantitative coupling. It can be inserted into the target sequence as a substitute for the dT residue. This makes it an essential tool for adding biotin to the desired positions within an oligonucleotide sequence. It complements the commonly used biotin phosphoramidite. The latter lacks the DMT group and can only be added to the 5' end of the oligonucleotide, thus bringing the synthesis process to an end.
