Singh, Agricultural Plant Stress Center, Chonnam National University, Gwangju 500-757, Republic of Korea. E-mail: adyasingh@hotmail.com We developed a method involving air-drying of a rubber suspension after fixation in glutaraldehydetannic acid and postfixation in osmium tetroxide for SEM observation. For TEM immunolabeling the suspension was air-dried after osmium-only fixation. Whereas conventional methods failed to satisfactorily stabilize rubber particles, the methods described here proved successful in preserving their integrity.
