(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 have to echo what others suggested, warmth is indeed what peppers seeds tend to love. Depending on the variety and the age of the seeds, they can take up to 2+ weeks to germinate. After many experiments, temperatures that work well for me are 78-82F when it comes to peppers.
