Dye | Abs/Em Max (nm) | Notes |
Acridine orange | 500/526 | green fluorescence bound to DNA, and red shift to ~650 upon association with RNA, uful for flow cytometry. |
FAM | 492/518 | Most widely ud green fluorescein, absorption overlaps the 488 nm spectral line of the argon-ion lar, prone to photobleaching, pH nsitive between pH 5-8,is widely ud for automated DNA quencing |
FITC | 494/519 | Subject to argon-ion lar, widespread u for hybridization, immunoreagent, protein quencing and FRET |
HEX | 535/556 | pH innsitive, ud for automated DNA quencing |
JOE | 520/548 | Intermediate-wavelength spectra, important dye for automated DNA quencing. |
Lissamine rhodamine B | 570/590 | Optimal for 568 nm excitation photostable,ud in confocal lar scanning microscope.easier to label protein than TMR. |
Pyrene | 340/378 Excimer:470 | Long excited-state lifetime, spectral shifts due to excimer emission,ud in protein comformation and oxygen nsors. |
ROX | 570/590 | spectra between Lissamine rhodamine B and Texas Red, ud in automated DNA quencing. |
TET | 521/536 | pH innsitive, ud for automated DNA quencing |
Tetramethyl rhodamine | 555/580 | pH innsitive , photostable,Widely ud for automated DNA quencing |
Texas Red | 595/615 | Suited for the Ar-Kr 568nm and He-Ne 594nm spectra, brighter and lower background than other red dyes as third label, ud in confocal lar scanning microscopes |
Dansyl Chloride | 372/ND | Environmentally nsitive, large stokes shift for protei quencing |
Dabcyl | 453/none | Broad absorption, no fluorescence, as a quenching group uful for fluorescence resonance energy transfer (FRET) |
CR-6G | 525/555 | Spectral between fluorescein and tetramethylrhodamine, good photostable, preferred nucleotide off protein |
Cascade Blue | 400/420 | Resistant to quenching upon protein conjugation, Water soluble. |
BODIPY R6G | 528/547 鞠九兵 | Substitute for rhodamine 6G,Uful for automated DNA quencing |
BODIPY FL | 505/513 | pH innsitive, narrow spectral bandwidth, uful for automated DNA quencing, preferred protein conjugation. |
Amino--coumarin | 345/445 | 微信如何贷款Widely ud blue fluorescent dye, visibly brighter and easier for microscopes |
