Second, optimize antibody dilutions by performing titration experiments; start with higher dilutions (1:2000-1:5000) and adjust based on signal-to-noise ratio. Third, enhance washing procedures by increasing the number of washes (5-6 times) and duration (10-15 minutes each) with freshly prepared TBST or PBST buffer. Fourth, pre-absorb the primary antibody with proteins from non-target tissues to reduce non-specific binding. Fifth, include detergents (0.1-0.3% Triton X-100) in antibody dilution buffers to minimize hydrophobic interactions. Sixth, use highly purified secondary antibodies with minimal cross-reactivity to plant proteins. Seventh, incorporate additional blocking steps with normal serum (5-10%) from the same species as the secondary antibody.
