- PVDF membranes (after protein transfer and rehydration of the membrane in 100% methanol followed by water) should be incubated overnight at 37°C in 1% calf intestinal alkaline phosphatase diluted in NE buffer 1 (NaCl 10 mM; Tris 5 mM, pH 7.9; MgCl2 1 mM; dithiothreitol 0.1 mM).
- Sister membranes should be incubated in the NE buffer only. Rinse three times in TBST.
- Block membranes in 5% milk in TBST.
- Incubate membranes overnight in primary antibody.
- Secondary antibody concentrations and detection protocol should be performed as usual.
