{"product_id":"live-watch-targeted-erna-assay","title":"Live Watch (Targeted eRNA Assay)","description":"\u003cp\u003eA DNA detection tells you a species' genetic material was in the water. It does not tell you why. A zebra mussel signal at a busy boat launch could mean an established colony — or a contaminated boat that visited last week. Those two situations call for very different responses, and Live Watch is built to tell them apart.\u003c\/p\u003e\u003cp\u003eLive Watch looks for the RNA of one named species, using a targeted assay. Because RNA begins degrading within minutes to hours of leaving a living cell, a positive result is strong evidence the organism is alive and active where you sampled, not just that its DNA passed through.\u003c\/p\u003e\u003cp\u003eIt also means eRNA cannot be collected the way eDNA is. Valid eRNA sampling requires high-volume pumped filtration to concentrate enough viable transcript signal, and immediate on-site chemical preservation to lock the snapshot before it breaks down. That is what the Osprey platform, supplied by our genomics partner, is built to do.\u003c\/p\u003e\u003cp\u003eUse it to confirm, not to screen: after a Species Watch or Lake Census detection, to check whether a treated or removed population is still active, or where a response decision depends on knowing the organism is alive. Sold in sets of three sampling locations — typically the detection site and two nearby.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOne of four genetic tests.\u003c\/strong\u003e “Census” reads the whole community; “Watch” looks for one named species.
