*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
