Purity standards for reagents are set by organizations such as ASTM International or the American Chemical Society.

Tools and reagents Nuclear transfer is a delicate process that is a major hurdle in the development of cloning technology.

Equipment for treatment and diagnostics, reagents, and consumable supplies were all bought to upgrade the technical facilities of the medical institutions providing this type of service.

That means there's no waiting for chemical reactions to take place, no need to use reagents that can run out and no need to be an expert to get actionable information.

And so we can encapsulate these regions of ultra conservation through evolution how these viruses evolved by just choosing DNA elements or RNA elements in these regions to represent on our chip as detection reagents.

After a period of doubt about the accuracy of NPT results, a new generation of machines and reagents seems to be gaining acceptance for its ability to deliver results close in accuracy to those of the lab.

The biology faculty of the University of Havana was prevented from obtaining from the companies Sigma and Clontec a set of reagents for extracting DNA and RNA from biological samples, which are of use in studies with applications in biotechnology. Although the financing for the acquisition originated in a Swedish funded project, the supplier refused to make the sale on the grounds of the embargo.
