(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.
Germination Time. Rosemary seed takes 15 to 25 days to germinate under ideal conditions. Plant the seed about 1/4 inch deep in a well-draining germination mix. Water thoroughly and place the seed tray on a heating mat. Only about 30 percent of the seeds can be expected to germinate even under the best conditions, so plant seeds thickly.
