BLAST Search


routine BLAST : Routine BLAST of allergen sequence search but omitted to display the results of high identity of short fragments.

FAO/WHO rules : By this special search, the results of Allergenia website would display different identity levels in 5 group columns: Column 1, a minimum of 35% sequence identities over a window of 80 amino acids of each query protein with an allergen; Column 2, Identities less than 35% over sliding windows of 80 amino acid segments of each query protein, but with at least one segment identity of eight contiguous amino acids; Column 3, Identities less than 35% for sliding windows of 80 amino acid segments of each query protein, but only with 7 amino acid exact match; Column 4, Identities less than 35% for sliding windows of 80 amino acid segments of each query protein, but only with 6 amino acid exact match; Column 5, Identities less than 35% for sliding windows of 80 amino acid segments of each query protein, but with no more than 5 amino acid exact match-- This design has been made on the basis of recent study which demonstrated that only 5 contiguous amino acid identities can also lead to cross-reactivity between the nonhomologous allergens.
