Used for electrophoretic separation of RNA and small DNA fragments. The 3% agarose concentration provides high resolution for nucleic acids in the range of 100–2000 base pairs. Pre-cast format with 8 wells ensures consistent gel quality and saves preparation time. Ideal for routine RNA analysis due to RNase-free formulation, preventing RNA degradation. Compatible with standard horizontal gel electrophoresis systems. TBE buffer system offers stable pH and good resolution for small to medium-sized fragments. Commonly used in molecular biology for PCR product analysis, restriction digestion verification, and RNA integrity checks.
