GIPSA Proficiency Program:  Historical Record
Protein-Based Testing
Percentage Correct for Each Biotech Event
  Corn Events Soybean Event
Month/Year Test Used T25 CBH351 NK603 Cry1Ab* Herculex MON863 CP4 EPSPS
September 2003 Protein (LFS) 83.3% 100.0% 100.0% 50.0% NR  NR 33.3%
April 2004 LFS 66.6% 66.6% 83.3% NR NR 66.6% 100%
*Cry1Ab is the protein produced in events MON810, E176 and Bt11, and it is impossible to differentiate among these events 
using a protein-based test.  In addition, the fortification level could be below the limit of detection for this test.
**NR indicates No Result was reported by the participant
Note:  In February 2003 this organization received corn samples for qualitative analysis and soybean samples for quantitative analysis
