Strategic Diagnostics, Inc. today announced the availability of two analytical test kits to detect the characteristic protein found in StarLink(TM) corn. The first test is a quantitative analytical method in a microtiter plate format for laboratory use. The second test is an easy-to-use, rapid, strip-based method suitable for use in the field. These methods have been fully validated by SDI for use in detecting Cry9C protein in grain. These tests are designed to allow end-users to rapidly check for the presence or absence of StarLink(TM) corn in grain samples. Validation for other uses is ongoing. 

An individual strip test is designed to detect Cry9C protein in grain samples at a concentration of
0.25%. However, precise sensitivity is dependent on customer specifications and sampling
procedures. The tests are capable of detecting concentrations of less than 0.1% using multiple
samples. The quantitative microtiter plate test has sensitivity of less than 0.1% using a single sample. The test is available through SDI and interested persons should contact SDI's customer service groups at (302) 456-6789 and (800) 544-8881. 

Richard C. Birkmeyer, President and CEO of Strategic Diagnostics, commented, "We are
delighted to complete the licensing agreement with Aventis so that we can offer this new test, which is part of a portfolio of SDI products marketed under the trademarks Trait Check(TM) and GMO Check (TM) by SDI and our marketing partner Agricultural Information Technologies through its newly formed business unit IdentityPreserved.com. We believe our tests are an important element in the StarLink(TM) Stewardship Program and we are pleased to offer this rapid, cost-effective analytical solution with the full support of Aventis. We believe the events of last week have raised the awareness for the need for rapid analytical testing of genetically modified grain.''
