Tips for Searching
Our Citations database contains references for peer-review journal articles that
cite the use of Promega products. There are three ways to search the database:
-
Enter keywords (including catalog numbers, product names or authors) into the
text field.
-
Select one or more Applications from the menu.
-
Use a combination of Application(s) and keyword text to search Citations.
For Citations using a particular Promega product we suggest that you search by
product name or catalog number. For searches with a broader scope, a good
strategy is to select one or two applications, view the results, and then
narrow the focus by adding keywords to the search criteria.
Citations that fit the search criteria will be displayed in reverse
chronological order (newer references first). We have not included Promega
literature about our products in this database of Citations. See
Publications or Protocols for additional
information on specific products.
Each return entry contains two main parts: the reference and a short note about
the use of Promega product.
Boolean Searching
The following Boolean connectors can be used: and, or, and not.
Examples:
| DNA and purification |
Containing both DNA and purification |
| DNA or purification |
Containing DNA or purification |
| DNA not purification |
Containing DNA, but without purification |
The search engine automatically inserts and between words if nothing else
is specified, so the connector and can be omitted in search terms. For
example, searching for RNA purification equals searching for RNA and
purification. If more than one application is selected, the search
engine will use or between applications for the search.
If you use more than one kind of a Boolean connector in your search term, you must
use parentheses to indicate precisely what you want to search for. For example:
| (DNA and purification) or luciferase |
Containing both DNA and purification or containing luciferase
only. |
| or |
|
| DNA and (purification or luciferase) |
Containing DNA only and containing purification or luciferase. |
Double quotes can be used to specify a phrase search (i.e., to find a string of
terms in an exact order). For example:
| "DNA purification" |
Instead of containing both DNA and purification,
the engine searches for the exact phrase DNA purification. |
Common words, such as in and the, are considered noise words and
are ignored in searches.
Word fragment search is not supported automatically. To search for a word
fragment, you have to use the wildcard symbol *
| * |
Can be in any position in the term and matches any
number of characters. Examples: apop* matches apoptosis or apoptotic;
*NA matches DNA or RNA; te*t
matches text or test. |
