Cat. No. Probe * Features of Carbocyanine or Aminostyryl Tracers
DiI and Analogs
D282 DiIC18(3) "DiI" Red-orange–fluorescent lipophilic probe; widely used as a neuronal tracer
D3911 DiIC18(3) "DiI" Large-crystal form of D282 to facilitate direct application of crystals to membranes
N22880 DiIC18(3) "DiI" NeuroTrace DiI tissue-labeling paste
V22885 DiIC18(3) "DiI" Vybrant DiI cell-labeling solution
D384 DiIC16(3) Shorter-chain DiI analog that may incorporate into membranes more easily than DiI
D383 DiIC12(3) Shorter-chain DiI analog that may incorporate into membranes more easily than DiI
D3899 FAST DiI oil Unsaturated DiI analog that reportedly migrates ~50% faster than DiI within membranes
D7756 FAST DiI Solid form of D3899 to facilitate direct application of crystals to membranes
D3886 Δ9-DiI oil Unsaturated DiI analog that may migrate faster than DiI within membranes
C7000
