4. 9 volumes saturated ammonium sulfate) and followed by dialysis against several changes of PBS. 5. 3. Add a drop of sodium azide solution and store at 4°C. 6. For the next use, warm the column and all buffers to room temperature. De-gas the buffers before running through the column to eliminate air bubbles. 3. Chicken Use of chickens for antibody production has been reported but not fully utilized in plant virology (1, 16). The concentration of chicken immunoglobulin Y (IgY, which is equivalent to mammalian IgG) in the yolk is essentially similar to (in some cases much higher than) the concentration of IgY in the serum.

6. Total RNAs extracted from symptomatic squash leaves using the Ultraspec RNA isolation system and primers WNSs67KS and WNSs1383cK were used to check the presence of the insert in the recombinant by RT-PCR. 7. 0% agarose gels by electrophoresis. Purification of ZYMVExpressed NSs Protein 1. 50 g Infected zucchini squash leaves were ground in 100 ml buffer A with a blender. 2. Extracts were clarified by centrifugation at 3,000 × g for 10 min, and supernatants were filtered through Miracloth. 3. The filtrates were treated with 1% Triton X-100 at 4°C for 30 min and then centrifuged at 30,000 × g for 30 min.
