Product overview
This product consists of 6 double-stranded DNA fragments: 2,000 bp, 1,000 bp, 750 bp, 500 bp, 250 bp, and 100 bp, mixed with loading dye. This product is used as a DNA molecular weight standard for agarose gel electrophoresis. The concentration of the 750 bp double-stranded DNA fragment in DL2000 DNA Ladder is 100 ng/5 μL, showing a bright band, the DNA concentration of all other bands is 50 ng/5 μL. This product is suitable for the analysis of DNA bands in agarose gel electrophoresis and is not recommended for polyacrylamide gel electrophoresis.
Features and applications
- Room-temperature stability: Remains stable for up to 6 months at room temperature, with sharp and clearly resolved bands.
- Ready to use: Premixed with loading dye for direct loading onto agarose gels.
- DNA fragment sizing by agarose gel electrophoresis
- DNA molecular weight reference
