What different tests
are a variety of procedures to test if a crop is genetically
modified (GM). Tests either test for the protein synthesized
by the inserted gene, or you can test for the inserted
tests are often used when unloading grain
at an elevator to verify the identity of the grain.
Strip tests are fast and require no laboratory setting.

tests also are quick in determining if
a grain is GMO but require more laboratory skills. Both
strip tests and ELISA tests test for the protein that
is formed by the inserted gene. With several ELISA tests
you can calculate the concentration of GMO in a grain
lot. BioProfile Testing Laboratories, LLC
offers ELISA testing.
(Polymerase Chain Reaction) is a patented
process (Applied Biosystems, CA) and tests if grain
has the inserted genes that make it a GMO. This manner
of testing is more costly because it requires expensive
laboratory equipment and skilled personnel. PCR testing
allows you to quantify the amount of GMO in a grain
lot, e.g. you can determine if the lot is below 0.5%
GMO contamination. PCR testing is the most sensitive
method of testing. End-users in Europe and Japan require
tests. Some laboratories will back up
their tests by germinating soybean seed and then applying
glyfosphate to determine the GMO content of the grain.
You can also quantify the GMO content of the grain lot
with this method. Germination tests are slow, up to
two weeks, to get results and require big enough samples
to adequately quantify the GMO content.
Testing Laboratories, LLC specializes
in PCR technology to test for GMOs. In our standard
PCR test, we test for the promotor, the gene of interest,
and the anti-biotic resistance gene to determine the
GMO content of a grain sample. We find that this approach
of testing is the most robust in the industry to test
