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(shù)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(xiàn)。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
