Tampões

Tampões

Resistentes a alterações de pH, os tampões protegem as amostras quando são adicionados ácidos ou bases. Disponíveis em pó e líquido, estes tampões rastreiam as proteínas de forma eficiente durante o isolamento e a separação por eletroforese. Também podem ser utilizados para calibrar e padronizar os medidores de pH, garantindo leituras precisas. As substâncias bloqueadoras impedem a ligação dos anticorpos aos locais livres na membrana, que produziriam um sinal de fundo interferente. Disponíveis em diversas concentrações para satisfazer qualquer necessidade, os tampões podem ser encontrados em formatos líquidos ou desidratados.
