Na,K-ATPase isoforms detected by Western analysis of human erythroid progenitor cells and mature human erythrocytes
| Cells | α1 | α2 | α3 | β1 | β2 | β3 | γ |
|---|---|---|---|---|---|---|---|
| Progenitors | + | − | + | + | + | + | + |
| Erythrocytes | + | − | + | + | + | + | + |
It is evident that the isoform composition of both types of preparations is the same, indicating that these cell types contain the α1, α3, β1, β2, and β3 isoforms, and the γ modulator of the Na pump.
