Tampão

Os tampões de microscopia mantêm um ambiente estável para a observação de espécimes biológicos. Garantem a integridade das amostras e condições óptimas para observações precisas.

Norman Good e colegas identificaram 20 tampões padrão em 1980, atualmente utilizados em microscopia para fixação de tecidos. Os tampões ideais para a preparação de amostras biológicas em microscopia eletrónica de transmissão (TEM) têm um pKa dentro da gama de pH quase neutro de 6 a 8. Os exemplos incluem PBS, Fosfato de Sørensen, Fosfato de Millonig, Cacodilato, PHEM, Tris, HEPES e PIPES.
