Used for electrophoretic separation of DNA and RNA fragments in molecular biology applications. The 3% concentration is ideal for resolving small DNA fragments in the range of 100–1000 base pairs. The pre-cast gel format saves time and ensures consistent gel quality, eliminating the need for manual gel preparation. Compatible with TBE buffer systems, it supports sharp band resolution during nucleic acid analysis. Commonly used in PCR product analysis, restriction enzyme digestion checks, and DNA fragment sizing. The 15-well comb allows multiple samples to be run simultaneously, making it suitable for medium-throughput lab workflows. Safe and easy to handle, it reduces exposure to hazardous chemicals like ethidium bromide during casting.
