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, MethodsNow
, 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
Continuing with our example above, you notice two
analyses of malathion in brassica cauliflower – one using
spectrophotometry and one using colorimetry. To help you
determine which method is best for your research and the
instruments and materials available to you, you can compare
up to three methods side-by-side. In this case, we can take
two possible methods, compare them to find which one is best
suited to replication in your lab based on the materials and
instrumentation required. One case uses potassium hydroxide,
the other potassium iodate. Which do you have more of on
