Alexa Fluor® 430 Carboxylic Acid, Succinimidyl Ester

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Amine-Reactive Fluorophores, Biotins, Quantum Dots, & Other Labels

The amine-reactive Alexa Fluor 430 carboxylic acid, succinimidyl ester and its conjugates exhibit the rare combination of absorption between 400 nm and 450 nm and fluorescence emission beyond 500 nm (excitation/emission maxima ~434/539 nm).

Oregon Green® 488 Carboxylic Acid, Succinimidyl Ester, 5-isomer

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Amine-Reactive Fluorophores, Biotins, Quantum Dots, & Other Labels

This single 5-isomer preparation of our proprietary, amine-reactive dye, Oregon Green 488 carboxylic acid, succinimidyl ester and its conjugates have green fluorescence similar to that of fluorescein but are more photostable. Additionally, Oregon Green 488 dye has a lower pK a than fluorescein (pK a = 4.7 versus 6.4 for fluorescein), making this bright dye less pH sensitive in the physiological range.

SNARF®-1 Carboxylic Acid, Acetate, Succinimidyl Ester - Special Packaging

Category: Products & Services > Labeling & Detection Products > Sensors & Indicators > Ion Indicators & Ionophores

To permit simultaneous long-term tracing of mixed-cell populations using different fluorescent colors, we have developed a probe whose applications should be similar to those of CFDA SE (commonly called CFSE). Cells labeled with our SNARF-1 carboxylic acid, acetate, succinimidyl ester have orange-red fluorescence that can be easily distinguished from that of cells loaded with green-fluorescent tracers such as CFDA SE.

Pacific Green™ Succinimidyl Ester, Triethylammonium Salt

Category: Products & Services > Labeling & Detection Products > Labels & Labeling Kits > Amine-Reactive Fluorophores, Biotins, Quantum Dots, & Other Labels

Pacific Green™ Succinimidyl Ester is a violet-excitable (411 nm) dye with an emission maximum at ~500 nm, allowing it to be used with other violet-excitable fluorophores (such as Pacific Blue™ or Pacific Orange™ dye) for multiparameter analysis using a single excitation source. As a class of compounds, succinimidyl esters offer an efficient and easy-to-use means for selectively linking a dye to accessible primary amine groups on proteins, modified nucleic acids, or other biomolecules. The covalent bonds formed are as stable as the peptide bonds used to link the amino acids within proteins. Pac...
