Blocking Buffers

The electrophoresis buffers maintain consistent pH levels during DNA, RNA, and other protein separation. Providing ions that transfer the applied current, the low charge solutions facilitate different molecular sizes to travel at various rates for analyses. Offering additional protection to proteins, the preparative substances prevent degradation for guaranteed sample viability and accurate testing. Available in various molecular weights, the best electrophoresis buffer can be selected based on the specific macromolecules being handled.
