Lumafluor公司的逆向示蹤產品RetroBeads™是逆向示蹤熒光微球，且也是目前證實有效的示蹤微球。該產品的有效性經數百篇從無脊椎動物到哺乳動物實驗的研究論文證實，正是靶點科技旗下Proven and Published®服務和產品質量理念的體現。RetroBeads™體內注射高度集中不易擴散，信號強，對活細胞或活體無毒，且存留時間大于一年，與大多順向示蹤劑、原位雜交檢測技術、免疫組化技術兼容。

RetroBeads™ from Lumafluor are 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.

For Reliable, Robust Retrograde Transport, There's Only One Choice: RetroBeads™ from Lumafluor. Only Retrobeads™ (regular and IX) from Lumafluor have been proven effective by hundreds of published papers in systems ranging from invertebrates to primates, and everything in between. 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

--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.]

--are specially prepared to facilitate adsorption of proteins and other bioactive compounds.

--are also more effective tracers in primate systems than standard
