However, frequently a X25 immersion objective will reveal very clearly labeled cells that lower power objectives miss. These caveats are especially true for green beads. Before deciding that an experiment did not work, examine sections in the vicinity of the injection site with immersion objectives. Numerous locally labeled cells should be present.
Additional information for green bead users: In work that has been done so far, it appears that younger animals transport the label better than older animals. In addition, tissue autofluorescence is lower in the younger animals. Therefore, it is advisable to use younger animals, if possible, in experiments involving green beads.
Because the green beads are excited at shorter wavelengths than red beads, tissue autofluorescence is a greater problem. Therefore, efforts to minimize autofluorescence will produce a better contrast signal. Ways to reduce autofluorescence include: 1) using thinner sections (e.g. 30 um rather than 40 or 50) 2) using younger animals, and 3) examining sections promptly after coverslipping (background increases over time).
InformationFor Reliable, Robust Retrograde Transport, There\"s Only One Choice: RetroBeads from Lumafluor.
RetroBeads from Lumafluor--the original microspheres for retrograde tracing and the only microspheres proven effective where it counts: in your experiments. Green and Red fluorescent RetroBeads are available exclusively from Lumafluor.
Do not be misled by the unsubstantiated claims of other suppliers!
No matter what they call their products, only Retrobeads from Lumafluor have been proven effective by hundreds of published papers in systems ranging from invertebrates to primates, and everything in between. Lumafluor Retrobeads : Highly confined injections--superb for detailed connectivity studies. Persist indefinitely ( 1 year!) in living cells, nontoxic. Compatible with most other anterograde tracers, in situ hybridization, and immunohistochemsitry.

Retrobeads IX: Retrobeads deliver bioactive agents (such as neurotrophins and neurotransmitter agonists/antagonists) to localized regions; retrograde transport allows determining which neurons were exposed to the agents [Riddle et al. Nature 378:189, 1995 and Quattrochi et al. Science 245:984, 1989]. Retrobeads IX are specially prepared to facilitate adsorption of proteins and other bioactive compounds. Retrobeads IX are also more effective tracers in primate systems than standard Retrobeads . 123
