Thank you for your question. We have not yet tested this antibody, Id2 (E-7): sc-398104, for use in pig samples so we do not recommend it for use with this species at this time. The antibody is raised against amino acids 105-134 at the C-terminus of Id2 of mouse origin. Based on sequence analysis, this sequence shares 90% sequence identity with Id2 of pig origin (protein accession number Q2VIU1). This is a high degree of identity, so there is a good chance that the antibody may also cross-react with pig.
