| SpCrossreactivity | The 28 AA human C28R2 sequence is 100% conserved in human Ca+-ATPase isoforms 1, 2, 3b, 96% in 1b, 92% in 4, and 85% in 3a/3b. It is also 100% conserved in mouse, and rat isoform 2. A high degree of conservation (77-100%) is also seen in Ca+-ATPase isoforms from many other species. Antibody cross-reactivity of C28R2 or its exchange inhibitory properties in various species has not been studied |
