(1942) used FITC-labeled antibodies to identify Pneumococcal antigens in infected tissue. Since then, improvements have been made in protein conjugation, tissue fixation methods, detection labels and microscopy, making immunohistochemistry a routine and essential tool in diagnostic and research laboratories.
Check daily for germination. Onion seeds germinate in five to 14 days, depending on the cultivar and the soil temperature. Move to a sunny location and keep the tops trimmed to a height of 4 inches. Keep soil moist.
Onions, planted from seed in full sun and well-draining soil, germinate within 21 days of planting. Harvest time depends on which type of onion is preferred. Scallions, or green onions, should be pulled when the bulbs are 1/2 to 1 inch in diameter, while fully mature onions are ready for harvest when the tops die off, in mid to late autumn.
