Conjugation Kits

Tetramethylrhodamine-5-maleimide is the purified single isomer of tetramethylrhodamine-5 (and 6)-maleimide mixed isomers. It is widely used for thiol modifications of peptides and proteins. It is preferred for some complicated biological applications where reproducibility is more critical than material cost since...

Sulforhodamine 101 is a fluorescence reference standard for measuring fluorescence quantum yield. It is also the key precursor used for preparing rhodamine 101 sulfonyl chloride (also called Texas Red(R), a trademark of Molecular Probes). This sulforhodamine 101 sodium salt is more water-soluble than the neutral...

Solvent: DMSO. Excitation (nm): 649 Emission (nm): 664 Extinction coefficient (cm-1 M-1): 250000. Coronaviruses (CoVs) can infect humans and multiple species of animals, causing a wide spectrum of diseases. In late 2019, a novel coronavirus, termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was...

Solvent: DMSO. Excitation (nm): 656 Emission (nm): 670 Extinction coefficient (cm-1 M-1): 250000 Quantum yield: 0.25. Coronaviruses (CoVs) can infect humans and multiple species of animals, causing a wide spectrum of diseases. In late 2019, a novel coronavirus, termed severe acute respiratory syndrome coronavirus 2...

ReadiLink(TM) xtra rapid antibody labeling kits require essentially only 2 simple mixing steps without a column purification needed. Preactivated iFluor(TM) 555 used in this ReadiLink(TM) kit is quite stable and shows good reactivity and selectivity with antibodies. The kit has all the essential components for...

Poly-HRP-antibody conjugates is considered to have the highest sensitivity in immunoassays where the sample is limited, or a target molecule is present at extremely low level. Buccutite(TM) Poly-HRP Antibody Conjugation Kit is designed for rapid preparation of poly-HRP conjugated antibodies. The kit provides the...

Ex: 623 nm. Em: 638 nm. Soluble in: DMSO. Our zFluorT serial dyes are developed to have the possibly highest photostability at a given wavelength compared to the other similar wavelength dyes on the market. zFluorT 633 has almost identical spectral properties to ATTO 633, ATTO 635 and Alexa Fluor® 633...

Ex: 780 nm. Em: 800 nm. Soluble in: DMSO. Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, and liver blood flow, and for ophthalmic angiography. It has a peak spectral absorption close to 800 nm. These infrared frequencies penetrate...

Ex: 648 nm. Em: 669 nm. Soluble in: DMSO. Our zFluorT serial dyes are developed to have the possibly highest photostability at a given wavelength compared to the other similar wavelength dyes on the market. zFluorT 647 has almost identical spectral properties to the popular Cy5® (GE Healthcare) and Alexa Fluor® 647...
