Buffertar håller pH värdet stabilt när syra eller bas tillsätts och skyddar på så sätt provet. Pulver- och vätskeform spårar effektivt proteiner under isolering och separation vid elektrofores. Saltbuffertar kan också användas för att kalibrera och standardisera pH-mätare för noggrann mätning. Blockerare stoppar antikroppar från att fästa sig på membranfria platser, något som skulle ge en störande bakgrund. Buffertar finns i olika koncentrationer, som olika fasta ämnen och vätskor.
