R-M-5444	Difluorocarboxyfluorescein NHS Ester, 5-isomer	Difluorocarboxyfluorescein NHS Ester, 5-isomer (Oregon Green™ 488 Carboxylic Acid, Succinimidyl Ester, 5-isomer equivalent) is an amine-reactive fluorinated analog of fluorescein that overcomes some of the key limitations of fluorescein, including greater photostability and a lower pKa (pKa ~ 4.7 versus 6.4 for fluorescein), making its fluorescence essentially pH insensitive in the physiological pH range. Difluorocarboxyfluorescein NHS Ester, is a preferred, routinely used fluorescent dye for labeling proteins, peptides and nucleotides.	price>
R-M-5445	Difluorocarboxyfluorescein Azide, 6-isomer	2’,7’-Difluorocarboxyfluorescein Azide,6-isomer (also under Oregon Green 488 Azide (Oregon Green™ 6-Carboxamido-(6-Azidohexanyl), Triethylammonium Salt), 6-isomer name) is a bright, green-fluorescent azide-activated probe that reacts with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free click chemistry reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. 2’,7’-Difluorocarboxyfluorescein fluorinated analog of fluorescein that overcomes some of the key limitations of fluorescein, including greater photostability and a lower pKa (pKa ~ 4.7 versus 6.4 for fluorescein), making its fluorescence essentially pH insensitive in the physiological pH range.	price>
R-M-5447	5-TAMRA Cadaverine	5-TAMRA cadaverine can used to modify carboxylic acid group in the presence of activators (e.g. EDC, or DCC) or activated esters (e.g. NHS esters) through a stable amide bond. It also can be reversibly coupled to aldehydes and ketones to form a Schiff base – which can be reduced to a generate stable amine derivative by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaCNH3). 5(6)-TAMRA cadaverine is a preferred, routinely used orange-fluorescent dye for staining proteins, it is rearly used for labeling peptides and nucleotides.	price>
R-M-5540	RADA	RADA is an orange-red TAMRA-based fluorescent D-amino acid. Suitable for labeling peptidoglycans in live bacteria. Incorporated into bacterial cell walls during synthesis. Suitable for prolonged exposure due to red-shift photophysical properties. Suitable for dSTORM and reSTORM. Displays good water solubility, photostability and thermostability.	price>
R-M1by-9077	3,6-Dichlorobenzene-1,2,4-tricarboxylic anhydride	3,6-Dichlorotrimellitic anhydride is the key precursor that is used for preparing a variety of dichlorinated fluoresceins and rhodamines such as TET and HEX. These chlorinated fluoresceins and rhodamines are widely used for labeling oligos and in DNA sequencing.	price>
R-M1by-9078	2,4-Difluororesorcinol ,CAS 195136-71-1	2,4-Difluororesorcinol is a precursor that can be used for preparing fluorescent dyes such as fluorescein, coumarin and resorufin analogs. It is the key precusor for preparing Pacific Blue dyes.	price>
R-M-5645	Tubulin Tracker Green	Tubulin Tracker ™ Green is a non charged, non fluorescent compound that can easily pass through the plasma membrane of living cells. After the dye enters the cell, the nonspecific esterase will cut the lipophilic blocking group to form a charged green fluorescent product. It can be used for live cell imaging.	price>
R-M1by-9125	Cyluc1,CAS 1247879-16-8	Cyluc1,CAS 1247879-16-8 is a synthetic cyclic alkylamino luciferin that exhibits superior properties in in in vivo imaging due to its red shift luminescence compared to D-luciferin. It has a higher affinity for binding to luciferase and releases about 5.7 times more light than amino luciferin, and 3.2 times brighter than D-luciferin. Its excellent light output can be maintained over a wide range (1-100) μM) .	price>
R-M2g-9181	Vat Blue 2	Vat Blue 2,cas29245-44-1 is an indigo derivative and also a dark blue 5,5- dibromo-4,4-dichloro indigo dye (dyne). We can mass produce (kg level), process scaling up, pilot supply, raw material supply, and intermediate production. Our production technology is mature and more cost-effective. Feel free to inquire at any time.	price>
R-M2g-9185	Fluorescein O,O-diacrylate,cas7262-39-7	Fluorescein O,O-diacrylate is a compound derived from the fluorescent dye fluorescein. This specific derivative is utilized in various applications, particularly in the field of fluorescent labeling and bioconjugation chemistry. Fluorescein derivatives like O,O-diacrylate are employed to label biomolecules, such as proteins and nucleic acids, due to their fluorescent properties. These compounds are often used as fluorescent probes in biological and biochemical research for detecting and visualizing specific molecules or structures. The acrylate groups in this compound make it suitable for polymerization reactions or for functionalization of other materials due to the reactivity of the acrylate functionalities. We can mass produce (kg level), process scaling up, pilot supply, raw material supply, and intermediate production. Our production technology is mature and more cost-effective. Feel free to inquire at any time.	price>
