| SpCrossreactivity | The 23 AA rat NCX12-P control peptide 100% conserved in mouse, dog, cat, 95% in human, rabbit, monkey, bovine, 86% in chicken, and 73% in frog NCX1. NCX11-P epitope is conserved in NCX isoforms 1-7 that have deletions or substitutions after ~600 aa. No significant sequence homology is detected with other NCX. Antibody cross-reactivity in various species has not been studied |
