Specificity:Recognizes hiNOS (985-1002) and rhiNOS (Type II). The reactivty of heNOS (1017-1034) and rheNOS (Type III) is ~60%. Does not react to hnNOS (1256-1273) and rhnNOS (Type I). It has been epitope mapped using 96 overlapping 18 amino acid long synthetic peptides which cover the entire 1153 amino acid length of hiNOS and was found to bind to a defined region of the hiNOS sequence, residues 985-1002.
