(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.
My seeds have been germinating for about 4 or 5 days now. I heard it takes about 2-7 days for the germination process to come to an end, from what I've read and heard. About 1 1/2 days after I started germination, one fat seed already began sprouting a root so I planted it immediately.
