Save time with a one-of-a-kind new solution to search and compare the largest collection of scientific methods


Every lab has different timelines, budgets, equipment, supplies and expertise. Planning an experiment using procedures not typically performed in your lab must take all of these factors into account. And while there is no shortage of online resources for lab protocols, the process of finding and vetting analytical methods suited for your lab can be time-consuming and tedious. In contrast, MethodsNowTM, a new solution from CAS, a division of the American Chemical Society, lets analytical scientists search and compare the latest published scientific methods quickly and efficiently.

Remarking on the difficulty of tracking down lab methods on the Web, Trey Thompson, a pharmacology researcher at the University of North Carolina at Chapel Hill said, “I look them (protocols) up in something like PubMed to find what methods have been used to get the data that I’m looking for. I also go to and look what the current clinical trial methods are to see if what I’m trying to do is still being used for popular research or not.”

MethodsNow solves Trey’s problem of having to search multiple sources by aggregating method information in one convenient location. Leveraging the work of CAS scientists, MethodsNow includes the latest published scientific methods with index terms applied for easy discoverability, allowing Trey to get to the lab faster. The methods focus on various scientific disciplines, including analysis of organic compounds, pharmacology, toxicology, food analysis, agriculture, water analysis and environmental analysis. MethodsNow provides access to thousands of disclosed procedures with a click of a button.

From the search screen in MethodsNow, you can conduct a keyword search, browse method categories or return to one of your recent searches. For instance, if you want to find methods to detect residual presence of a common pesticide, such as malathion, on vegetables, enter “malathion vegetable” in the search field of MethodsNow, and be presented with over one hundred different methods relating to your pesticide of interest. The auto-suggest function in the search field can help you identify possible search terms as you type, and filters let you quickly hone in on the results you seek. You can then click the Method Category and select “Pesticide Residue Analysis” to focus your search.

Click “View All” on the “matrix” drop-down to see a list of different vegetable options. Select “Cucumis sativus”, also known as cucumber, to see the studies on this topic. Finally, in the Technique section, you can see the variety of analytical techniques covered by these documents.

MethodsNow provides step-by-step instructions for analytical methods in areas like pharmacology, high performance liquid chromatography (HPLC), food analysis, natural product isolation analysis and water analysis, and many more. Each method includes the source of the information, as well as materials, equipment used, conditions and step-by-step instructions.
