DNA Gel Electrophoresis Ladders are precision-designed molecular weight standards that enable accurate sizing of DNA fragments in agarose gel electrophoresis. Available in multiple formats—50 bp, 100 bp, and 1 kb—they provide defined reference points for low, medium, and high-range DNA analysis.
The 50 bp ladder offers ultra-high resolution for small amplicons, the 100 bp ladder serves as a versatile marker for routine PCR applications, and the 1 kb ladder supports the analysis of large genomic and long-range PCR fragments. Together, these ladders ensure precise interpretation of DNA results across research, biotechnology, and diagnostic workflows.
All GCC DNA Ladders—including 50 bp, 100 bp, and 1 kb formats—are supplied in a convenient ready-to-use formulation. Each ladder is pre-mixed with appropriate loading dye and buffer, making additional preparation unnecessary. Users can dispense the ladder directly into gel wells. This format minimizes error, enhances reproducibility, and simplifies electrophoresis workflows across research and diagnostic applications.
