alkaline blotting

  • 1 щелочной блоттинг

    [англ. blotting — промокание, получение реплики пятен]
    вариант метода Саузерн-блоттинга (см. Саузерн-блоттинг), в котором после разделения фрагментов ДНК с помощью электрофореза в агарозном геле их депуринизируют с помощью кислоты in situ, а затем переносят на нейлоновую мембрану с буфером, содержащим 0,4 М NaOH. Щелочь обеспечивает фиксацию ДНК на нейлоновом фильтре без дополнительного УФ-облучения, которое снижает эффективность гибридизации. Метод предложен К. Ридом и Д. Манном в 1985 г.
