Puffer

Die gegen pH-Änderungen beständigen Puffer schützen Proben bei Zugabe von Säuren oder Basen. In Form von Pulvern oder Flüssigkeiten werden sie effizient zur elekrophoretischen Isolierung und Trennung von Proteinen eingesetzt. Die salzhaltigen Puffer können auch zur Kalibrierung und Standardisierung von pH-Messgeräten verwendet werden, um genaue Messergebnisse zu gewährleisten. Blocking-Puffer verhindern die Anbindung von Antikörpern an freie Membran-Bindungsstellen, die ansonsten einen störenden Hintergrund verursachen würden. Die Puffer sind je nach Bedarf in verschiedenen Konzentrationen sowie in flüssiger oder getrockneter Form erhältlich.
