These savings enable analytical laboratories to respond to the rising pressure for faster, more affordable mycotoxin testing and greater productivity without increasing their environmental impact or compromising the quality of their data. The result is a mycotoxin testing process of enduring value to analytical laboratories, their end users, and the larger world.
8. A nucleic acid concentration high enough to force the DNA out of solution (if the conc is not high enough, you can add a carrier nucleic acid or glycogen to enhance the recovery).
Platts is actively considering whether and when to evolve the FOB Singapore Gasoil benchmark assessment to the 65 ppm sulfur grade. This white paper aims to take the discussion further on the evolution of Asia’s gasoil benchmark.
Hi there, I am extracting from tissues and using isopropanol, but after adding the 99% isp the usual big white fluffy DNA strands isnt there anymore, needed to centrifuge at high speed to get the DNA pellet, which after specing turns out to be 755ug, which is lots, my question is why dont i see the strands of DNA PPT out of solution anymore?! Did this in a batch of six and none of them ppted out with a strand, just turned cloudy and needed my solutions off? Using Qiagen puregene kit, basically, there is lysis buffer, protein ppy soln, and isp..Thats it.
Over the last five years, the use of methanol in China has undergone a radical shift with the introduction of methanol-to-olefins technology. Now an exclusive S& P Global Platts statistical analysis shows that changes in polypropylene prices in China can be used to help understand changes in methanol prices in a statistically significant manner, with evidence from industry sources pointing to Chinese MTO plants as the mechanism.
This report examines both the short and medium-term implications for the UK gas system of the extended maintenance at Rough, and analyses the opportunities open to other supply sources that could cover the loss of UK storage capacity during the next winter season.

Viewed within the context of this burgeoning risk landscape, test methods designed to confirm a single toxic threat loom as obstacles to sustainability. When six or seven mycotoxins are in question, methods that require a separate test run for each target analyte create a sinkhole of inefficiencies. Over the long term, this approach is likely to devour enormous amounts of time, manpower, and laboratory consumables. Ultimately, it’s bound to prove as unfit for the unfolding regulatory scene as it is for an economic climate and a natural environment that call for doing more with less.
Feedback from the market suggests that there’s a dislocation between the published contract price and the actual price that has been paid. As a result we recently made a change to our methodologies. We see this as essential to bringing transparency to the polymer contract market. This report explains the detail of these changes.
