(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.
I planted just the root end of the bulb in vermiculite but you could use soil. It took just a few days for the onion leaves to start growing. From seed, it could take a week or more for the seeds to germinate and emerge from the soil.In south Texas, onions seeds are planted in late summer, grow all winter and harvested in May and June.
