Your datasheets states this antibody was raised against "aa 1-70 of ACTH." However, ACTH (AKA corticotropin) is only a 38 aa protein (aa 138-176 of POMC) that is formed from cleavage of POMC, see the uniprot file below. I wanted to confirm if this antibody was raised against amino acids 1-70 or 138-176 of POMC.
The ACTH antibodies were raised against 39 amino acid ACTH hormone. The Specification sheet specifies the rangefrom where the peptide was selected. In this case the 39 AA are the complete ACTH hormone.

The peptide was conjugated with a carrier protein for making ACTH antibodies.
