(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 temperature: 50 F to 85 F-Will germinate at temperatures as low a 40 F. Will germinate in about a week at 75 F, with adequate moisture. Days to emergence: 7 to 21. Seed can be saved 3 years. Carrots are slow to germinate (1 to 3 weeks), and often germinate unevenly over a period of several weeks.
