(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.
If you dry your onions indoors, be sure to spread them out in a well-ventilated area with plenty of room for airflow between the onions. Drying indoors may take longer than outdoor drying, but 2-3 weeks is usually sufficient with full circulation.
