SUMMARY
Incubating a filter with primary antibody for two overnights before adding a secondary antibody in Western blotting is not advisable. Extended incubation increases the risk of non-specific binding, which can compromise detection accuracy. Instead, it is recommended to block the membrane with a standard blocking solution, rinse with TBST, and store it sealed at 4°C until the primary antibody incubation can be performed according to the protocol. This approach allows for optimal results while accommodating scheduling constraints.
