English to Spanish Medical Medical (general) defined species- and organ-specific pancreatic elastase peptide sequences

Buenos días,

Espero que puedan ayudarme con la siguiente expresión al español: “defined species- and organ-specific pancreatic elastase peptide sequences”, relacionada con un ensayo ELISA para detectar elastasa pancreática en el diagnóstico de insuficiencia pancreática. Muchas gracias:

“The Pancreatic Elastase ELISA is based on a double-sandwich technique for the quantitative determination of human pancreatic elastase in feces. Two polyclonal antibodies are recognizing several different epitopes on defined species- and organ-specific pancreatic elastase peptide sequences. XYZ is using polyclonal antibodies which recognize several different epitopes in parallel to reach a higher diagnostic sensitivity and specificity.”
