| SpCrossreactivity | The COX21-P peptide sequence is identical in mice, rat and human. The antibodies react with COX-2 of murine, ovine, bovine and human origin. Cross-reactivity with cell lines such as 3T3 cells, BMMC, L-929, PC-12, C127, CEF-147 is also expected.. There is no reactivity to purified COX-1 |
