Description
Description
Use our molecular ruler to accurately assign molecular weights to DNA fragments separated by gel electrophoresis. Perfect 50% GC content eliminates spurious migration due to sequence variation, ensuring that the fragments migrate exactly according to their specified size. See Recommended Gel Types. Store product at 4°C.
