Conjugation Kits

There are several ways of labeling an oligonucleotide with fluorescein. The choice of label is diversified further, depending on the spectral requirements. 5-fluorescein-CE phosphoramidite, derived from the single isomer 6-carboxyfluorescein, 5-hexachlorofluorescein-CE phosphoramidite (HEX) and...

Ex: 583 nm. Em: 603 nm. Soluble in: DMSO. Although Texas Red® is the most popular labeling reagent of sulfonyl chloride, it is quite unstable in water. Even in anhydrous DMF, Texas Red® tends to give a very complicated reaction mixture. It reacts with thiols, alcohols, phenols, aliphatic amines and aromatic amines...

Readilink(TM) protein labeling technology is the most robust and convenient tool for preparing fluorescent antibody conjugates used for fluorescence imaging and flow cytometry applications. ReadiLink(TM) Rapid AF555 Antibody Labeling Kit provides the most convenient tool for making Alexa Fluor(R) 555-labeled...

Readilink(TM) protein labeling technology is the most robust and convenient tool for preparing fluorescent antibody conjugates used for fluorescence imaging and flow cytometry applications. ReadiLink(TM) Rapid AF594 Antibody Labeling Kit provides the most convenient tool for making Alexa Fluor(R) 594-labeled...

Correction Factor (260 nm): 0.31. Correction Factor (280 nm): 0.12. Extinction coefficient (cm -1 M -1): 76000. Excitation (nm): 498. Emission (nm): 526. 6-OG488 azide has the same chemical structure to that of Oregon Green(TM) 488 azide. It is a convenient tool to introduce the fluorophore of Oregon Green to a...

Biotin and biotin derivatives bind with high affinity to both avidins and streptavidins. Biotin alkyne can be readily conjugated to many biomolecules through the well-known click chemistry.

Soluble in: DMSO. Digoxigenin (DIG) is a hapten, a small molecule with high antigenicity, which is used in many biological detections similarly to other popular haptens such as 2,4-Dinitrophenol (DNP) and biotin. Typically, digoxigenin is conjugated to a macrobiomolecule (e.g., proteins, nucleic acids, etc) to be...

Correction Factor (260 nm): 0.3. Correction Factor (280 nm): 0.11. Extinction coefficient (cm -1 M -1): 73000. Excitation (nm): 499. Emission (nm): 520. Quantum yield 0.92. XFD488 contains the same fluorophore of Alexa Fluor(R) 488. It is a bright, green-fluorescent dye with excitation ideally suited for the 488 nm...

Extinction coefficient (cm -1 M -1): 1500001. Excitation (nm): 558. Emission (nm): 574. DY547 CEP (DyLight 547 phosphoramidite) is an excellent replacement to the commonly used Cy3 phosphoramidite. Two cyanine derivatives, Cy3 and Cy5 phosphoramidites, are the most popular fluorescent labeling reagents for preparing...

7 Dye qPCR Calibration Plate contains seven spectral calibration plates with seven separate dye standards (TAMRA, SYBR, FAM, JOE, NED, ROX, and VIC). It can be used to maintain your 7500 Real-Time PCR system with Fast 96-well block. For most of qPCR instruments, the necessary calibrations should be run at least...
