The protein products of the inserted genes (cry1F and pat) are not, in any way, proteins that regulate the normal metabolic pathways of plants and therefore will not interfere with the plant’s normal growth and development.  No nucleic acid sequences that code for a protein toxic to humans or antibiotic resistance were introduced into 1507 maize.  Similarly, no significant homology was demonstrated for the cry1F and pat with known allergens and neither protein was stable in a simulated gastric fluid.  Both proteins have little probability of being allergenic.
The key nutrients present in TC1507 and non-transformed maize are comparable.  Two potential anti-nutrients, phytic acid and trypsin inhibitor were found to be within the acceptable range for both conventional and transformed maize grain.  Similarly, trypsin inhibitor levels in both 1507 maize and the isoline were below the limit of quantification.  This confirms that no unusually high levels of trypsin inhibitor are present in 1507 maize.
