Frequently Asked Questions
What are electrophoresis buffers used for?
Electrophoresis buffers create the ionic environment needed for the migration of charged molecules, such as DNA, RNA, or proteins, through a gel matrix during electrophoresis.
What’s the difference between TAE and TBE buffer?
TAE (Tris-acetate-EDTA) offers faster migration and is ideal for downstream gel extraction or enzymatic applications. TBE (Tris-borate-EDTA) provides better resolution for small fragments and maintains buffering capacity over longer runs.
How do I choose the right electrophoresis buffer?
Buffer choice depends on the type of molecule (DNA, RNA, protein), gel type, desired resolution, and compatibility with downstream recovery or enzymatic steps.
