buffers
Al resistir los cambios de pH, los tampones protegen las muestras al añadir ácidos o álcalis. Los tampones en polvo y líquidos rastrean eficazmente las proteínas durante el aislamiento y la separación por electroforesis. Los tampones salinos también se pueden utilizar para calibrar y estandarizar medidores de pH y obtener lecturas precisas. Las sustancias bloqueantes impiden la adhesión de los anticuerpos a los sitios libres de la membrana, lo que produciría un fondo interferente. En diversas concentraciones para adaptarse a cualquier necesidad, los tampones pueden presentarse en formato líquido o deshidratado.
